The convection heat transfer plays an essential role to many heat transfer situations by different ways. Convection comprises both the fluid flow as well as heat flow. Computational fluid dynamics is very useful to determine the behaviour of heat flow and fluid flow. Fins are employed in situation where it is desirable to increase the heat transfer. Fins may be stationary or moving as in case of electric motor and bike engines. The heat transfer depends on heat transfer coefficient of medium, thus the correlation for Nusselt number and Reynolds number with respect to location of the body has been studied. Fin heat transfer is either steady state or transient according to situations and involves natural convection and forced convection to enhance heat transfer. The aim of this paper, to review the work carried out in the field of fin heat transfer. Literature reviews of research work pertaining to heat transfer analysis in fins of various profiles are described.
