In present study, the effect of dimple shapes on the flow and the heat transfer of between two dimple plate-fins were numerically analyzed. The dimples were applied to extend the fin surface area and to promote turbulent flow near the plate-fin. The ratio of the depth (d) to the diameter (D) of dimples is one of important parameters, which affect flow and heat transfer as geometric variables. As simulation results, the case with ratio d/D of near 0.24 was worst on average Nusselt numbers within test range from 0 to 0.4.
