Rate of heat transfer is an important parameter of heat exchangers, mostly it is affected by fins geometry. To achieve maximum heat transfer, shape of the fins plays a major role. In the present work an attempt is made to study the heat transfer performance in terms of temperature difference and pressure drop of pin fin heat sink with constant base heat flux is studied using commercial CFD software (ANSYS). Three geometries of pin fin have been designed by keeping the same cross-sectional area. CFD analysis have been carried out in both free and forced convection with transient formulation. Results have been compared with circular shape fin.
