| Dr. M. Sreenivasa Rao | Structural and Theoretical Investigations of a Novel Hexanuclear Lanthanum (III) Cluster Self-Assembled Through a Functionalized β-diketone ligand via Atmospheric CO2 Fixation | Trapping atmospheric carbon-di-oxide (CO2) by lanthanide oxo-hydroxo clusters continuously receives a great deal of attention from the viewpoint of environmental concerns. Functionalized β-diketone ligands plays an important role in assembling lanthanide oxo-hydroxo clusters. Reaction between LaCl3 6H2O and phenolic β-diketone ligand 1-(2‑hydroxyl phenyl)-3-phenyl-1;3propanedione (HO-DBM) in methanol solvent in presence of triethylamine base yielded a novel hexanuclear cluster [La6(O-DBM)6 (HO-DBM)4 (μ3 single bond OH) (μ2 single bond OH2) (HCO3) (OH2)2 (MeOH)2]. The compound has been structurally characterized by single crystal X-ray diffraction analysis; it reveals that 1 consist of a La6 assembly template by (µ4 single bond HCO3) − anion. It was anticipated that the bicarbonate anion that bridge lanthanum units is introduced via spontaneous fixation of atmospheric carbon dioxide in the basic medium. Interestingly the bicarbonate anion exhibits a new bridging mode µ4-η1: η1: η1: η1. We applied the fundamental concept of bond valance sum (BVS) method in establishing the level of protonation of the various oxygen atoms in this cluster including water; hydroxide; bicarbonate; methanol and ligand. The values obtained for the title compound totally validate the crystal structure. Further the stability of the structure has been investigated by theoretical studies; the geometrical parameters (bond length and bond angles) are in line with the experimental observation. |
| Mr. B. Joga Rao | Investigation of the effect of adding carbon nanotubes; lower and higher level alcohol additives; in yellow oleander methyl ester-diesel blend on diesel engine performance | The project is to determine the overall performance of a compression ignition engine (CI) employing a B30 (30% Yellow Oleander Methyl Ester (YOME) and 70% diesel) sample including nano and alcohol additives. Initially; the surface-modified carbon nanotubes (CNTs) (at a dosage of 60 mg/L) are sonicated in the B30 blend for 30 mins at 40 kHz and termed B30CNTs60. It was found to be quite stable as evidenced by characterization. The B30CNTs60 blend is then blended with a fixed volume (10%) of n-Butanol; iso-Butanol; and Dimethyl Carbonate (DMC); and referred to as B30CNTs60+n-Butanol10%; B30CNTs60+iso-Butanol10%; and B30CNTs60+DMC 10%. The physicochemical properties of all fuel samples met ASTM criteria and samples were experimented on a 1-cylinder; 4-stroke diesel engine under varying loads. The results revealed that the B30CNTs60+DMC 10% blend enhanced heat release rate (HRR); cylinder pressure (CP); and brake thermal efficiency (BTE) by 11.2%; 8.64%; and 11.92%; respectively. Furthermore; with B30CNTs60+DMC 10% blend; the combustion duration; brake specific fuel consumption (BSFC); carbon monoxide (CO); hydrocarbons (HC); carbon dioxide (CO2); nitrogen oxide (NOx); and smoke opacity were reduced by 10.9%; 15.62%; 18.24%; 18.78%; 8.12%; 6.75%; and 10.92% respectively. Finally; the B30CNTs60+DMC 10% blend was suggested to use in CI engines. |
| Dr. D. Santha Rao; Mr. K. Sreenivasa Reddy | Parametric optimization of AA6061-Cu friction stir welded joints with boron carbide particle reinforcement | The objective of this work is to improve the mechanical properties of friction stir welded square butt joints of AA6061 and pure copper employing activated flux of B4C micro powder. Rotational speed; transverse feed and tool penetration depth were optimized using Taguchi method to produce joints devoid of defects. Rotational speed was found to be the most influential process parameter in achieving the higher ultimate tensile strength and has 49% contribution followed by feed and penetration depth. Model predictions for the optimal strength were validated and found to have 5 % variation. Highest ultimate tensile strength and micro Vickers hardness of 259.57 MPa and 98.58 HV respectively were obtained for joints made with speed; feed and penetration depth of 1250 rpm; 20 mm/min and 0.1 mm respectively. The microstructural analysis revealed that B4C particles were distributed uniformly in the stir zone which could be the reason for improved mechanical properties. |
| Mr. B. Joga Rao | Effects of staby dispersed carbon nanotube additives in yellow oleander methyl ester-disel blend on the performance; combustion; and emission characteristics of a CI engine | In this investigation; the influence of carbon nanotubes (CNTs) on the overall performance of a diesel engine using 20% (by volume) of yellow oleander methyl ester and 80% diesel (Y20) with and without CNT nano additives was studied. The surface modification of CNT nanoparticles was observed; using ultraviolet–visible spectrometry; in the Y20 with different concentrations of QPAN 80 surfactant. The optimal concentration is determined to be 1:4. Nano additives were blended in Y20 blends at concentrations of 25; 50; and 75 ppm employing an ultrasonicator with optimal ratio. These samples were examined for physicochemical properties and tested in a compression ignition (CI) engine. Significant enhancements in performance and emission parameters were observed for the Y20C50 blend: Brake thermal efficiency improved by 15.5%; and we observed a reduction in brake-specific fuel consumption by 20.57%; carbon monoxide by 26.8%; unburnt hydrocarbon by 35.7%; and nitrogen oxides by 13.2%. Similarly; the addition of CNTs in the Y20 blend improved cylinder pressure; heat release rate; and rate of pressure rise and reduced ignition delay and combustion duration. In summary; CNTs were discovered to be suitable fuel additives for the Y20 blend to improve overall engine performance and reduce emissions. |
| Mr. B. Joga Rao | Influence of nano additives on performance; combustion; and emission characteristics of diesel engine using tamarind oil methyl ester-diesel fuel blends | Hazardous emissions majorly NOx and the poor performance of alternative fuels (biodiesel/its blends) are global concerns; as fossil fuel depletion and rising energy prices encourage researchers to rely on alternative energy sources with the addition of nano additives in the recent decade. The current experimental study investigates the performance; combustion; and emission characteristics of biodiesel-diesel mixtures dispersed with titanium dioxide (TiO2) as a fuel additive on a 1-cylinder diesel engine. TiO2 was dispersed in a Tamarind Oil Methyl Ester (TOME)-diesel blend (B20) in three concentrations of 40; 80; and 120 ppm via ultrasonication in the presence of QPAN80 surfactant to enhance the stability of the prepared fuel sample. A ratio of 1:4 TiO2:QPAN80 was found to produce the highest stability and homogeneity which is evidenced by the characterization of TiO2. The engine tests revealed that the greatest decrement in BSFC; CO; HC; and NOx was observed as 15.2%; 15.2%; 11.10%; and 9.06%; and the maximum BTE; HRR; and CP were improved by 9.76%; 50.32 J/degree; and 50.32 bar for the B20T80 blend correlated with B20 blend. Thus; the inclusion of TiO2 nano additives improved overall engine performance and decreased emissions of CI engines significantly. |

| Dr. D. Santha Rao | Effect of nano particle on mechanical properties of activated tungsten gas welding of austenite stainless steels 316L and optimization of process parameters | Austenite stainless steel 316L was developed to improve corrosion resistance and is widely used in automobile components; thermal power plants; and pressure vessels due to their superior toughness and intergranular corrosion resistance. The austenite stainless steel 316L has a low carbon content of 0.03%; which helps in minimizing harmful carbide precipitation during welding. The joint strength of welded joints is poor unless proper care is taken. As a result; an attempt was made to use an activated Tungsten Inert Gas (A-TIG) welding procedure to improve the joint strength of butt welded joints of austenitic stainless steel 316L. The process parameters such as current; the volume of flow; and filler diameter were chosen in the study and generated an L 9 design matrix using MINI Tab software. The welded joints were prepared as per the design matrix using the activated flux of aluminum oxide nano powder as per the combination of process parameters. The mechanical tests such as tensile strength; hardness; and impact strength were evaluated and microstructural evaluation of welded joints was also assessed. The input parameters were optimized for better tensile strength of joints using Taguchi S/N analysis. It is found from the optimization that the highest ultimate tensile strength of 690.40 MPa was obtained at a current of 90 A; shielding gas flow of 13 l min–1; and filler material diameter of 2.5 mm. The model was also validated by conducting experiments. |
| Dr. G. Ramakrishna | Effect of HSS and WC drill bits on form and hole precision in Ti-6Al-4V drilling operations | In many manufacturing applications; the form and hole precision of a product can directly affect its functionality. High form and hole precision are key indicators of product quality. If a product is manufactured with low precision; it can lead to defects; errors; and a reduction in overall product performance. Manufacturing with high precision can help reduce waste and improve efficiency. By minimizing errors and producing high-quality products consistently; manufacturers can increase their throughput; reduce costs; and ultimately improve their bottom line. The aim of this study is to evaluate the differences in vibrations and form that are induced by using HSS and WC drill bits to perform drilling operations on Ti-6AL-4V work material. In the current study; measurements of form error in the work piece as well as vibrations of the tool that is being used throughout the drilling process are obtained. The diameter of the drill bits that were taken is 10 millimetres. The increasing frequency and vibration amplitude both lead to an increase in the amount of form error in the work material; as well as a displacement of the hole centre and a movement of the tool position away from its centre. Form error; such as the measurement of roundness is taken into consideration. |
| Dr. A. Babji | Experimental investigations into engine characteristics fuelled with hibiscus coconut biodiesel and its blends | The world's fossil fuel sources are decreasing rapidly. Rising population growth needs alternative fuels. Biodiesel is an alternate and sustainable fuel obtained from different feedstocks. In this work; biodiesel was made from hibiscus-coconut oil by the transesterification technique. The aim of the present research is to investigate the emissions; combustion and performance characteristics of a single-cylinder variable compression ratio diesel engine fuelled with hibiscus-coconut biodiesel blends. The blends of B05 (5% biodiesel and 95% diesel); B10 (10% biodiesel and 90% diesel); and B15 (15% biodiesel and 85% diesel) were prepared with hibiscus-coconut biodiesel and diesel. The engine is running at a speed of 1500 rpm and a compression ratio of 17.5:1 at various loads. The experimental findings are compared with those of diesel fuel. The brake thermal efficiency (BTE) and brake power (BP) were improved by 2.48% and 1.78% for blend B15 at peak load. The brake specific fuel consumption is the same as that of diesel. The maximum cylinder pressure is 63.82 bar. Carbon monoxide; hydrocarbon emissions and smoke have decreased by 18.03%; 13.79% and 52.71%; respectively. There is a marginal increment in nitrogen oxides of 14.37%. The blend B15 is acceptable for diesel engines as a renewable fuel. Thus; the findings show that; without any modification to the engine; the blend B15 can be utilized as an alternate fuel for diesel engines. |
| Dr. A. Babji | Optimisation of performance parameters of a variable compression ratio diesel engine with hibiscus cocos nucifera biodiesel using Taguchi method | The present experimental work describes the performance of a variable compression ratio diesel engine with hibiscus cocos nucifera biodiesel. The Taguchi method is used to optimise engine performance parameters. Compression ratios from 15:1 to 18:1; loads of 6; 9; and 12 kg; and blends B05; B10; B15; B20; B25; and diesel are the input parameters. Brake power; brake thermal efficiency; and mechanical efficiency were chosen as performance parameters. The optimum values are 23.7250% brake thermal efficiency; 3.41667 kW of brake power; and 70.0600% mechanical efficiency with a load of 12 kg; a compression ratio of 16:1; and blend B20. The CO emissions of blend B25 were reduced by 36.36% at a compression ratio of 18:1 when compared to diesel at full load. NOx emissions were increased with an increase in compression ratio and blend ratio. The mass fraction burned is higher for B20 and B25 with an 18:1 compression ratio. |

Santha Rao | Evaluation of mechanical properties of aluminium alloy (AA 6082) reinforced with Rice husk ash (RHA) and Boron carbide (B4C) hybrid metal matrix composites using stir casting method | Aluminum alloys are commonly employed in shipbuilding and automotive manufacturing units. The mechanical properties of alloys; such as strength and hardness; can be improved by adding reinforcement to the matrix material. Stir casting is an improved method for uniform dispersion of particles over conventional casting methods. Therefore; an effort is made to fabricate aluminium alloy (AA 6082) composites with different ratios of hybrid reinforcement of Rice Husk Ash (RHA) and Boron Carbide (B4C) reinforcements. The mechanical properties of composites such as tensile strength; hardness; flexural strength; and impact strength were evaluated. The microstructural properties of composites were evaluated using a scanning electron microscope to determine the dispersion of particles in the matrix material. It is found that tensile strength; hardness were improved by 20% as well as the uniform distribution of reinforcement particles in composites. |

| Dr. M V S Babu | Accuracy detection of coronary artery disease using machine learning algorithms | For more than 50 years; coronary artery disease—which includes a variety of disorders; such as blocked or restricted coronary arteries—has been the primary cause of mortality in the US. Most cardiovascular diseases can be avoided; they can be determined by looking at risk factors. When assessing a person's electrophysiologic health; an electrocardiogram (ECG); a commonly available test; can be helpful in assessing their risk of cardiovascular disease. The automated and highly linked nature of ECG recordings makes them a good candidate for machine learning analysis. For the framework under discussion; this study compares and illustrates the advancements above conventional techniques. The suggested framework offers a novel method of assessing the severity of cardiac illnesses by combining machine learning techniques based on blockages with conventional survival analysis. |
| Dr. Tankeshwar Prasad | Epoxy/imidazole functionalized silica epoxy nanocomposites: mechanical and fracture behaviour | In this work; the mechanical and fracture performance of epoxy nanocomposites consisting of epoxide and imidazole functionalized silica nanoparticles has been studied. The post-synthesis grafting method was utilized to functionalized SiO2 nanoparticles with GPTMS (GGS) and used them as reinforcement (0–2 wt%) in epoxy resin. The cure behavior of nanocomposites demonstrated that the composite has excellent cure capability at 0.5 wt% of GGS. The composite containing 0.5 wt% of GGS exhibited significant improvement in tensile strength (~65 %) and modulus of toughness (~272 %); respectively. Additionally; the flexural strength; flexural modulus; and work of flexural were enhanced by ~48; ~50; and ~48%; respectively. Interestingly; the GGS showed its tremendous potential to improve the fracture toughness (K1C) and the fracture energy (G1C) of the nanocomposite by ~97 and ~292 %; which is also evident by the study of cure behavior. The fractography analysis endorsed the enhancement of material properties due to the use of GGS in the epoxy matrix. Failure investigation examined under FESEM elucidated forced the crack to move around the poles of the nanoparticles due to better interfacial adhesion. Hence; GGS nanoparticle has the potential to use as an excellent cost-effective reinforcement for the epoxy matrix to mitigate the brittle failure in epoxy composites. |

Santha Rao | Improvements in mechanical properties of aluminium alloy-titanium di boride and boron carbide hybrid composite produced through friction stir processing route | Aluminium alloys finds many applications in automotive; aerospace and ship building industries. Among all series AA 5083 alloys are commonly used in ship building industry but possess inferior mechanical properties which are replaced with aluminium alloy composites due to high strength to weight ratio. The present work is focussed to produce aluminium alloy composites with hybrid reinforcement Particles using friction stir processing route. The different proportions of boron carbide and titanium di boride particles are used as hybrid reinforcement particles. The aluminium alloy composites are fabricated by different proportions of reinforcement particles. The properties of fabricated composites such as ultimate tensile strength; micro Vickers hardness and impact strength are evaluated. The mechanical properties are improved and found that highest values of mechanical properties are obtained for 75% TiB2 + 25% B4C hybrid reinforced composite. The microstructural evaluations of composites are analysed using optical and scanning electron microscopy. It is found that hybrid reinforcement particles are uniformly distributed in the stirring zone without any micro defects. |

| Mr. B. Jogarao | Production; Performance and Emissions of Bio Diesel from Mixture of Animal Waste Fats and Degradation of Bio Diesel Over Time | This research investigates using a mixture of animal fat waste as a source for biodiesel production. It will explore how well this waste can be converted into biodiesel through a process called transesterification. The researchers will then assess the fuel's performance in engines by looking at factors like its ignition (cetane number) and flow (viscosity). Environmental impact will be considered by comparing exhaust emissions from the biodiesel to regular diesel fuel. Finally; the study will examine how the biodiesel itself degrades over time under different storage conditions to ensure it remains usable for extended periods.

| Mr. K. Sreenivasa Reddy | Experimental Study on the Thin-Walled Structure with Novel Multiple Cells under Axial Loading and Bending for Crashworthiness | This research explores a novel design to improve the crashworthiness of thin-walled structures; often used in energy-absorbing parts like car crumple zones. The project investigates a new multi-celled thin-walled structure under two crash scenarios: axial compression (direct impact) and bending (sideways force). The researchers will likely create thin-walled tubes with a unique internal compartmentalization design and then subject them to controlled crushing forces in both axial and bending directions. By measuring and analyzing the energy absorbed by the tubes during each crushing scenario; the study aims to determine how the multi-celled design affects crashworthiness. The goal is for this new design to absorb more energy upon impact compared to traditional thin-walled tubes; potentially leading to safer vehicles and structures in collisions. |
| Mr. Sk. Nayeem | Optimization of Convergent-Divergent Taper Angle with Combustion Chamber of Rocket Engine through Numerical Analysis | This research focuses on optimizing a crucial part of a rocket engine: the convergent-divergent (C-D) nozzle. This funnel-shaped component accelerates hot exhaust gases out of the engine; generating thrust. The C-D nozzle has two angled sections: a convergent section that initially increases pressure and velocity; and a divergent section that allows gas expansion for further acceleration. Researchers will use computer simulations to analyze how different combinations of these angles affect the nozzle's performance. The goal is to find the ideal angle combination that maximizes both thrust; the force generated by the engine; and efficiency; which means converting the most fuel energy into exhaust velocity. An optimized C-D nozzle can significantly improve a rocket's performance by increasing thrust for better acceleration and payload capacity; while also enhancing efficiency for lower fuel consumption and potentially longer range. |
| Mrs. E. Nirmala Devi | Experimental Examination on Forced Convection Heat Transfer in Laterally Perforated Finned Metal Matrix Composite Heat Sink | This research explores a novel design for heat sinks used in electronics cooling. It focuses on Metal Matrix Composite (MMC) heat sinks; where aluminum is reinforced with another material for improved thermal properties. The unique feature is laterally perforated fins - fins with holes punched sideways through them. Scientists will create MMC heat sinks with various hole configurations and test them under forced air convection at different speeds. The experiment aims to find the optimal fin hole design that achieves the best balance between heat transfer efficiency; crucial for keeping electronics cool; and pressure drop; which refers to the air flow resistance through the heat sink (ideally low for quiet operation). A successful design could lead to more efficient cooling solutions for electronic devices; potentially improving their performance and enabling more compact heat sink designs. |
| Mr. M. Balakrishna | Performance Analysis of Parallel and Counter Flow Heat Exchanger with Square Twisted Pipe | This research compares the performance of heat exchangers using square twisted pipes in two flow configurations: parallel and counter flow. Heat exchangers transfer heat between fluids; and square twisted pipes; with their helical twist; improve heat transfer compared to regular pipes. Parallel flow has both fluids entering on one side and flowing together; while counter flow has them entering from opposite ends and flowing against each other. Researchers will test these configurations by measuring heat transfer rate; pressure drop (resistance to fluid flow); and effectiveness (heat exchanger's ability to use the temperature difference). Counter flow typically offers better heat transfer; but this study will determine the specific difference for square twisted pipes. They'll also compare pressure drops; as counter flow's potential benefit might be offset by requiring more pumping power. The goal is to find the flow arrangement that offers the best balance between heat transfer and pressure drop for these unique pipes. Square twisted pipes themselves promote better heat transfer due to turbulence within the fluid. This research can provide valuable data for designing and optimizing heat exchangers in various applications; leading to more efficient thermal management systems. |
| Mr. G. Ramakrishna | Improvement of Hardness and Impact Strengths by Banana and Sisal Fibre Reinforced Epoxy Composites Filled with Groundnut Shell Ash | This research explores creating biodegradeable composites with improved hardness and impact strength.

Groundnut shell ash; a waste product from peanut processing; will be added as a filler to see if it improves the composite's mechanical properties. The researchers will create composite samples with different combinations of fibers; resin; and ash; and then test their hardness and impact strength. If successful; this study could lead to new biocomposites with better mechanical performance for various applications. The use of natural fibers and waste materials also promotes environmental sustainability by reducing reliance on non-renewable resources. |
| Dr. K. Hari Siva Phaneendra; Mr. G. Ramakrishna | Experimental Study on the Change in Hardness of Structural Steel (SA516) Post Fire Accidents | This research investigates how fires affect the hardness; and consequently the strength; of a specific type of structural steel commonly used in pressure vessels and boilers - SA516 grade steel. Hardness refers to a material's resistance to permanent dents or impressions. Scientists will heat steel samples under controlled conditions mimicking real fire scenarios; likely varying temperatures and durations. After the simulated fire; they will measure the hardness of the heat-treated steel. Understanding how fire exposure changes hardness is crucial for evaluating the remaining structural integrity of steel components in buildings or pressure vessels after a fire. The ultimate goal is to establish a connection between the fire's temperature and duration; and the resulting decrease in hardness of SA516 steel. This data can then be used to predict how much the structural performance of SA516 components might decline after a fire. This research can provide valuable information for engineers and firefighters to assess fire damage and ensure the safety of structures built with SA516 steel. |

Mr. K. Venkateswara Rao | Effect of Cerium Oxide Nano Additives on the Performance of a Hazantus Bio Diesel in a 4stroke DICI engine | This research explores how tiny cerium oxide particles (nanoparticles) can improve the performance and reduce emissions of engines burning Hazantus biodiesel, a specific type of biofuel. These nanoparticles are added to the biodiesel and then tested in a 4-stroke diesel engine. Cerium oxide might act as a catalyst, helping the fuel burn more completely, which could lead to both increased engine power and better fuel economy. Additionally, these nanoparticles have the potential to reduce harmful pollutants in the engine exhaust, such as hydrocarbons, carbon monoxide, and nitrogen oxides. The study will determine how much cerium oxide needs to be added to achieve the best results for engine performance and reducing emissions. If successful, this research could lead to a cleaner and more efficient way to use Hazantus biodiesel in everyday diesel engines, improving both engine performance and air quality. However, it's important to note that this is a relatively new area of research, and the long-term effects of using nanoparticles in engine fuels are still being studied. |
Mr. Sk. Nayeem | Heat Transfer Phenomenon of Fluids in Corrugated Plate Heat Exchanger | Corrugated plate heat exchangers (CPHEs) excel at transferring heat between fluids due to the unique phenomena happening within their corrugated plates. Unlike flat plates in traditional designs, CPHEs use thin metal plates with a wavy or corrugated pattern. This increases the surface area for heat transfer between the hot and cold fluids. More importantly, the corrugations disrupt the smooth flow of the fluids, creating turbulence. Turbulent flow mixes the fluids more effectively, leading to a faster exchange of heat. The corrugations also extend the flow path of the fluids within the exchanger, giving them more time for heat transfer. Additionally, these channels can induce secondary flows, further enhancing mixing and heat transfer across the entire flow area. These heat transfer enhancements translate into several benefits. CPHEs can achieve a higher heat transfer rate with a more compact design compared to flat plate exchangers, making them more efficient. The corrugations can also help maintain a relatively low pressure drop despite the longer flow path, reducing the pumping power required. However, factors like the corrugation angle and flow rate can affect heat transfer. A steeper corrugation angle creates more turbulence for better heat transfer but might also lead to a higher pressure drop. Similarly, a higher flow rate enhances heat transfer but increases pressure drop. Overall, the corrugated plate design disrupts flow, increases surface area, and promotes turbulence, resulting in a significant improvement in heat transfer efficiency compared to traditional flat plate heat exchangers. |
Mr. G. Ramakrishna | Advancement of Mechanical Assets of Banana Fiber Reinforced Epoxy Composites Loaded up with Ground nut Shell Cinder | This research explores creating bio-based composites with improved mechanical strength. It focuses on banana fibers, a natural and renewable resource, as the reinforcing element within an epoxy resin matrix. Groundnut shell cinder, a waste product from peanut processing, will be added as a filler to see if it can further enhance the composite's mechanical properties. The researchers will create composite samples with different combinations of fibers, resin, and cinder. Then, they'll test the mechanical performance of these composites, focusing on properties like tensile strength (resistance to pulling forces), flexural strength (resistance to bending), and impact strength (ability to absorb impact without breaking). If successful, this study could lead to the development of new biocomposites with improved mechanical properties for various applications. Additionally, it promotes sustainability by utilizing natural fibers and a waste product, reducing reliance on non-renewable resources. |
Mr. Sk. Nayeem | Enhancement of Weld Bead Hardness by Employing Random Vibration During Arc Welding | This research explores a new technique to improve the strength of welds created with arc welding, a common metal joining method. During arc welding, intense heat melts the metals together to form a weld bead. As the weld cools, it can shrink and develop internal stresses that weaken it and increase the risk of cracks. Here, scientists will investigate using random vibrations during the welding process, either on the workpiece or the welding torch itself. They expect these random vibrations to improve the weld's strength in two ways: by refining the grain structure of the weld bead (leading to better strength and lower stress) and by reducing the formation of cracks during cooling. To assess the effectiveness of this method, researchers will measure the hardness of the weld bead, a good indicator of its strength. They will compare welds created with and without vibration. If successful, this random vibration technique could be a simple and cost-effective way to improve weld strength in various industries. It wouldn't require major modifications to existing welding equipment, making it potentially easier to implement. Overall, this research explores a promising approach to creating stronger welds by introducing random vibrations during arc welding. |
Mr. M. Balakrishna | Experimental Evaluation for the Performance of VCR Diesel Engine by using CalophyllumInophyllum Bio Diesel with Nano additives of Aluminum oxide | This research explores whether tiny aluminum oxide particles (nanoparticles) can improve the performance of a VCR diesel engine when used with Calophyllum Inophyllum biodiesel, a plant-based fuel alternative. VCR engines can adjust their compression ratio, which allows researchers to find the optimal setting for each biodiesel blend. The scientists will create biodiesel blends with different nanoparticle concentrations and test them in the VCR engine under controlled conditions. They expect the nanoparticles to act as a catalyst, helping the biodiesel burn more completely. This could lead to both increased engine power and better fuel economy. Additionally, the aluminum oxide might reduce harmful pollutants in the engine exhaust, particularly smoke. By measuring engine performance, fuel efficiency, and exhaust emissions at different compression ratios for each fuel blend, the study will determine if these nanoparticles can make Calophyllum Inophyllum biodiesel a more viable fuel option for VCR diesel engines. If successful, this research could contribute to cleaner and more efficient engines using biofuels. However, it's important to note that the long-term effects of using nanoparticles in fuels are still being investigated. |
