Abstract: 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 aluminium alloy haschemicalcompositionofAl-Cu-Si Mg.ThedensityofADC12alloyisverylesscomparedtocastironresulting less weight of the engine.

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. Result shows that at 80 km/hr wind velocity heat transfer rate (120w/m2K) in rectangular fin greater than Masao Yasida (118w/m2K) in cylindrical fin.
