Abstract: The heat transfer rate depends on the vehicle velocity, fin geometry and ambient temperature. Increase the heat transfer coefficient and surface area of object increase heat transfer. Effects of the number of fins, fin pitch and wind velocity on air-cooling were investigated using experimental cylinders for an air-cooled engine of a motor cycle. The purpose of this experimental work is to study the forced conjugate heat transfer process taking place in engine cylinder block with varying wind speeds ranging from 40 km/hr. to 80km/hr., varying environmental conditions, various fin pitch and fin width. ADC12 Material is used by the Engine developers of 4-stroke. ADC12 aluminum alloy has chemical composition of Al-Cu-Si-Mg. The density of ADC12 alloy is very less compared to cast-iron resulting less weight of the engine. We have to design 3D model of the actual engine cylinder block of 4-stroke bike Engine has been drawn in Ansys 15.0. The Average heat transfer coefficient for the surface of the engine cylinder block has been calculated with the help of commercially available CFD tool ANSYS Fluent.
