Dimples play a very important role in improving the heat transfer in our day to day life. Dimples on the surfaces refer to recessions or notches formed on the surface. Dimples are used for increasing the surface area available for heat transfer as a result of which there is enhancement in heat transfer. Some typical examples of using dimples to enhance heat transfer are turbine blade cooling, tubular heat exchangers in chemical and textile industries, automotive radiators etc. In the present study, a numerical analysis is carried out to analyse the characteristics of heat transfer and flui d flow for various dimple shapes.Three shapes of dimples selected are elliptical, semi-circular and circular. Heat transfer rate is found to be maximum in case of circular dimples.
