Computational simulation of IC engine cooling using different materials for different shapes of fins: a comparative study

Abstract

Internal combustion (IC) engines are always exposed to extreme temperatures and thermal stresses. So, cooling the internal combustion (IC) engine is necessary to operate. The fins are used in engines to disperse the heat produced by the engine, especially in 4-stroke bike engines. The main focus of this research is to analyse and compare the thermal properties of the IC engine, such as temperature and total heat flux, by varying the shape and materials of four-stroke bike engine fins. In this study, Beryllium oxide (BeO) was proposed as an engine fin besides a few traditional metals. To obtain various temperatures and maximum total heat flux results, a four-stroke 125cc HERO GLAMOUR BS 6 motorcycle engine for various fin shapes such as circular, parabolic, wavy and slotted fins and different materials such as Aluminium 6061, Aluminium 2014, Beryllium oxide (BeO) and Silicon Carbide-Aluminium 2124 (SiC-Al 2124 25%) alloys used in this study. The best performance in case of maximum heat flux was found 8.417% more for Beryllium oxide (BeO) compared to Aluminium 6061 in circular fins.
