INVESTIGATION OF STRUCTURAL AND THERMAL ANALYSIS OF DRONE PROPELLER MATERIALS Dr.N. Tiruvenkadam, S. Gowri Shankar, P. Mahes Kumar, S. Gowtham Journal of Physics Conference Series, 2024 Drones, also known as unmanned aerial vehicles (UAVs), have become an Irreplaceable part of modern-day society. They are used for various operations such as delivery, surveillance, defense, and rescue. One of the most important parts of the drone that lifts, thrusts or balances the drone is its propeller. The weight of the drone is one of the important aspects that affects the efficiency of the drone, and the variation in speed may damage the drone propeller, or harsh environmental changes also affect the propeller. So, the material used must be able to withstand these effects such as carbon fiber, and nylon. The various material is analyzed using the ANSYS software to identify the structural and thermal properties of drone propellers at various speeds to identify the most satisfactory material for drone propellers. The result is verified by Ashby method of material selection. The experimental value is validated using the statistical analysis using python programming. As a result, carbon fiber is proven to be the most suitable material for high-speed drone propeller than the nylon.
Thermo-mechanical Analysis K. Ananthakumar, S. Sathish, P. Parthiban, N. Tiruvenkadam, M. Baskaran Friction Stir Spot Welding Metallurgical Mechanical and Tribological Properties, 2024 Friction stir spot welding (FSSW) is considered as a solid-state welding process, and it has the potential to replace methods such as riveting and resistance spot welding in some cases. Understanding the working principle of this intricate process, which includes frictional interaction, large temperature gradients, and significant distortions, is crucial. There are supposed to be several assumptions and ideas on the mechanics of heat production and material distortion during the FSSW process, but a consensus has not yet been reached. In this process, the flow of material has the biggest impact on the joining quality. The temperature-sensitive mechanical qualities have a direct impact on the material distortion and flow in both the close and distant fields of the weld. Therefore, from the perspectives of parameter optimization and mechanism comprehension, understanding thermo-mechanical responses is crucial. To address the mechanisms of heat production and linked thermo-mechanical responses of the workpiece and the impact of tool revolution and plunge rates, the FSSW process is theoretically and experimentally investigated. The relevance of contact circumstances at the tool-workpiece interface is highlighted, and an easy conceptual mechanism for how process parameters affect physical phenomena is described.
Experimental investigation of a novel alcohol fumigation in a single-cylinder constant speed diesel engine M. Bharathiraja, R. Venkatachalam, A. Murugesan, N. Tiruvenkadam International Journal of Ambient Energy, 2017 Biofuels play an important role as alternate fuel in diesel engines. In this paper, alcohol fumigation on a constant speed single-cylinder diesel engine is experimentally investigated. Fumigation is a method by which volatile fuels are injected into the intake manifold. Previously carburation and injection arrangements have been used for fumigation. In this work, computer control injection using LabVIEW software is attempted for alcohol fumigation and common rail is used to inject at same pressure always. Ethanol and methanol at different rates are used as fumigation fuels. The performance and emission characteristics are studied with and without fumigation. Fumigation increases specific fuel consumption (SFC), carbon monoxide emission and hydrocarbon emission. Fumigation decreases brake thermal efficiency at low load, carbon dioxide and smoke. Fumigation increases SFC at medium and high load conditions. The results show that fumigation replaces diesel up to a certain percentage and reduces both nitrogen oxides and smoke.
Experimental analysis of exhaust gas after treatment system using water scrubbing in a single cylinder diesel engine for diesel and biofuel blends M. Bharathiraja, R. Venkatachalam, N. Tiruvenkadam Transportation Research Part D Transport and Environment, 2016 A low-cost exhaust gas after treatment system called water-scrubbing is attempted in this paper. An emission treatment setup is fabricated, which is installed in the exhaust of the engine. This takes the exhaust gas and sprays water in the exhaust and passes it through the chamber containing silica gel. An attempt is made to investigate experimentally the performance and emission characteristics of a direct injection (DI) diesel engine, with and without water injection at the exhaust using diesel fuel (DF), diesel-Karanja oil blend (DKB) and diesel-Jatropha oil blend (DJB). The exhaust gas after treatment system helps to reduce NOx, CO and Particulate matter. The performance of the engine has also been monitored to determine whether the engine has any decrease in performance when the setup is used and it is found that there is no change in the engine performance.
Development of optimum friction new nano hybrid composite liner for biodiesel fuel engine N. Tiruvenkadam, P.R. Thyla, M. Senthilkumar, M. Bharathiraja Transportation Research Part D Transport and Environment, 2016 This work presents the preparation of aluminum (Al) 6061 nano hybrid composite samples reinforced with equal weight percentage of nano-ZrO2, micro-SiC, micro-Gr particles of 0%, 0.75%, 1.5%, 2.25%, and 3% using stir casting method. Friction characteristics of the composite samples under reciprocating conditions were studied at 125 °C using L27 orthogonal array and Taguchi method. The results of analysis of variance showed the influencing parameter for friction coefficient in the order of applied load and reciprocating sliding speed, followed by sliding distance and percent reinforcement. Hence, the total combined reinforcement sample of 6.75% was found to be optimum in terms of frictional characteristics and tensile strength. It was selected to synthesize lightweight nano hybrid composite cylinder liner (NL) and to replace the present cast iron cylinder liner (CL) used in biodiesel engine application. The developed NL had a 43.75% reduced weight than the currently used CL. Neat diesel and biodiesel from Jatropha oil and its diesel blends were used as test fuels. Experimental results proved that NL improved brake thermal efficiency, in-cylinder pressure, heat release rate and reduced carbon monoxide, hydrocarbon, and smoke emission in comparison with the existing liner. The results also showed that emission of the oxides of nitrogen (NOx) increased marginally with the new liner. Thus, the newly developed NL was found suitable for both diesel- and biodiesel-operated internal combustion engines.
Synthesis of new aluminum nano hybrid composite liner for energy saving in diesel engines N. Tiruvenkadam, P.R. Thyla, M. Senthilkumar, M. Bharathiraja, A. Murugesan Energy Conversion and Management, 2015 This work aims to replace the conventional cast iron cylinder liner (CL) in diesel engine by introducing lightweight aluminum (Al) 6061 nano hybrid composite cylinder liner (NL) by analyzing the performance, combustion, and emission characteristics of an engine. NL was fabricated by bottom pouring stir casting technique with nano- and micro-reinforcement materials. Experimental results proved that the use of NL increased brake thermal efficiency, in-cylinder pressure, heat release rate, and reduced carbon monoxide, hydrocarbon, and smoke emission in comparison with CL. However, oxides of nitrogen slightly increased with the use of the new liner. No differences in wear or other issues were noted during the engine teardown after 1 year of operation and 2000 h of running. Thus, NL has been recommended to replace the CL to save the energy and to reap environmental benefits.

Development of energy saving and environment friendly aluminum hybrid composite materials for vehicle applications N. Tiruvenkadam, P.R. Thyla, M. Senthilkumar, Thomas Don Bosco, A. Srikanth, S. Syed Ismail Faiyaz Advanced Materials Research, 2013 Our environment is majorly polluted by the release of hazardous gases into the atmosphere mainly from automobiles. The day-by-day increase in the usage of automobiles on the roads and decrease in the natural fuel source stresses engineers and scientists to develop engines with better fuel efficiency and reduced negative impact on environment. This could be feasible by controlling the engine tribological parameter using composite material. Clearly it is by reducing the weight and friction in the engine by applying suitable composite material and thereby reducing the wear, it can easily control the hazardous emissions to the environment and thereby keeping the environment safe.
Development of multipurpose reciprocating wear tester under various environmental parameters N. Tiruvenkadam, P. R. Thyla, M. Senthil Kumar, N. A. Kader, V. K. Pradeep, R. Vishnu Kumar, N. Sasikumar 2013 International Conference on Energy Efficient Technologies for Sustainability Iceets 2013, 2013 Friction and wear study of sliding surfaces plays a prominent role in the development of materials for various applications. The development of a low-cost multipurpose reciprocating tribometer at constant sliding speed to study the tribological properties of a material under dry, wet and high temperature conditions is presented in this paper. The tribometer has the ability of changing its stroke length in three levels viz. 85mm, 100mm and 120mm. The principle of operation consists of sliding counter surface against a stationary test samples under load. EN8 steel plate which acts as a counter surface, reciprocates with the help of crankshaft mechanism where the sample to be tested kept stationary in contact with the moving part. The testing of the material can be carried out at with variable loads to simulate real time scenarios. Load is applied as a dead weight and temperature sensor is used to find variation in temperature during testing. Strain gauge is used to find the frictional force between the materials. The prototype model of this tribometer is developed to achieve the tribological properties of the materials.
