Parametric Study on Fin Heat Transfer for Air Cooled Motorcycle Engine 2005-26-361

The cooling system is an important engine subsystem. The air cooling mechanism of the engine is mostly dependent on the fin design of the cylinder head and block. In the present paper an effort is made to study the effect of fin parameters on fin array heat transfer. Two and three dimensional conjugate heat transfer analyses have been performed using commercially available computational fluid dynamics (CFD) codes.
For a given heat flux, the fin profile and fin array parameters could be optimized in a better way by numerical simulation methods. CFD could be used to determine optimal values of the fin parameters, upstream of design process. Different trends of these parameters are observed and the values which give optimized fin surface from the thermal point of view at a given heat flux are determined.
