Abstract

Abstract: The current research article investigates the variation of heat flux with geometric modification on the re-entrant type piston bowl by varying bowl depth by computational domain. The contribution of ceramic coating on heat flux is also investigated in this research report. Computational study was carried out by using ANSYS 19.2 software in order to obtain the augmented results. The variation of piston bowl depth of Re-entrant type piston is accomplished as there is a novel need to study the variation in heat flux of piston at different bowl depths. The impact of the thickness of the ceramic coating is also evaluated. The focus of this article is to study the effects of combustion on the piston of a compression ignition engine. It was noticed that with the decrease of bowl depth and addition of ceramic coating there is a decrease in heat flux. Around 27.75% depreciation in the heat flux was noticed for the uncoated piston with a bowl depth of 15mm in comparison with 27 mm bowl depth and a 25% decrement with the addition of a ceramic coating of 0.4 mm and also a 55% decrement in the heat flux was observed with 1mm coating to the piston with 15 mm bowl depth in reference to 27 mm bowl depth of respective coating thickness. Disparity of maximum heat flux and heat losses with increasing bowl depth is also analyzed in the inquiry.
