Application of Optimal Space Filling Optimization Technique in Design Optimization of Engine Cylinder

Abstract

The engine cylinder is one of the vital components of an automobile. The cooling of engine cylinder is generally achieved with the aid of fins (or extended members). The design of fins have significant effect on heat dissipation characteristics of engine cylinder and therefore it’s imperative to evaluate the effect of fin dimensions on thermal dissipation characteristics.The objective of current research is to investigate the effect of fin dimensions on temperature distribution across engine cylinder fins. The design of engine cylinder and analysis is conducted in ANSYS FEA software. The effect of fin dimensions on heat flux and temperature distribution is evaluated using response surface optimization (RSO). The simulation results have shown that intersection zone of cylinder and fins have maximum heat dissipation as compared to other regions. The optimization process enabled to evaluate the effect of each design variable on heat dissipation characteristics. For total heat flux, the fin1dia has lower sensitivity percentage of 58.093 and fin2dia has higher sensitivity percentage of 74.996. The higher sensitivity percentage of fin2dia signifies that fin2dia has higher effect on heat flux of engine cylinder as compared to fin1dia.
