Exploration into assessing the mechanical characteristics of PETG pieces through the use of 3D printed material element tribology Sk. Avinash Kapil, M. Harika Chowdary, A. Babji, K. Prabhuchand, Peyyala Pramod Kumar Journal of Physics Conference Series, 2024 Additive manufacturing techniques like 3D printing make it possible to quickly and affordably create complexly formed bodies. It is particularly helpful for engineering applications like quick prototyping and rapid manufacturing. Using a heated nozzle arranged in three axes, filament is dispensed using the widely utilized fused deposition modeling (FDM) technique. The filament hardens as it leaves the nozzle. The study presented in this article examined the mechanical characteristics (primarily the elastic modulus and basic tensile strength) of elements printed using the fused deposition modeling (FDM) process from two different materials: unreinforced polyethylene terephthalate glycol (PETG) and glass-fiber reinforced PETG. The study compares the characteristics of PETG with and without the inclusion of glass fiber, outlining the advantages and disadvantages of the materials mentioned. The collected data can be utilized to model the characteristics of 3D printed elements and aids in quantifying the mechanical properties of PETG pieces.
Combustion Characteristics of a Variable Compression Ratio Diesel Engine Using Hibiscus Cocos nucifera Biodiesel and Taguchi Optimization Alapati Babji, Govada Rambabu, D. Balaji Naik, Sowmya Jonnagiri Journal of Mines Metals and Fuels, 2023 Biodiesel is a sustainable and renewable fuel to replace the conventional diesel. Biodiesel produced from hibiscus cocos nucifera oil was employed in a variable compression ratio diesel engine. The combustion characteristics of an engine were studied with different blends at various compression ratios 15, 16, 17 and 18. Experimental outcomes are compared with diesel fuel. The cylinder pressure is improved for blend B20 at compression ratio 18. The cumulative heat release is improved for blend B5 at compression ratio 17. Net heat release is highest for B10 at CR15. The mean gas temperature for B5 blend at compression ratio 17 has a maximum. To optimise combustion parameters, the Taguchi method was applied. The optimal values of the combustion parameters are 65.65 bar cylinder pressure, 7.26 bar/deg rate of pressure rise, 75.46 J/deg net heat release, 0.96 KJ cumulative heat release and 1424.54℃ mean gas temperature respectively, at maximum load, 16:1 compression ratio, and B20 blend using the Taguchi technique.
Experimental investigations into engine characteristics fuelled with hibiscus coconut biodiesel and its blends Alapati Babji, G. Rambabu, B. Devaraj Naik, A Mehta, N Mehta, et al. International Journal of Advanced Technology and Engineering Exploration, 2023 The requirement for energy on the globe is enormous. Fossil fuels are the primary source of energy. Fossil fuel plays a leading role in the global energy scenario [1]. Crude oil is expected to become extremely scarce and expensive [2]. Petroleum based fuels are used in industries, transportation, power plants and agricultural sectors, respectively [3]. Fossil fuels are finite and the use of fossil fuels results in pollution and global warming too. Carbon dioxide, nitrogen oxide, volatile compounds, and hydrocarbons (HC) are produced by fossil fuels during combustion. There has been a surge in demand for alternate energy sources [4]. Vegetable oils create engine problems like injector blockage, piston rings sticking and deposits because of high level viscosity and less volatility.
Optimisation of performance parameters of a variable compression ratio diesel engine with hibiscus cocos nucifera biodiesel using Taguchi method Alapati Babji, Govada Rambabu, Dhanavath Balaji Naik, Gandi Siva Kumar International Journal of Ambient Energy, 2022 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.
