Dimples play a really important role in heat transfer enhancement of electronic cooling systems, heat exchangers, etc. This work mainly deals with the experimental investigation of forced convection heat transfer over circular & oval-shaped dimples of various diameters on a flat copper and aluminum plate under external streamline flow conditions. Experimental measurements on heat transfer characteristics of air (with various inlet flow rates) on a flat plate with dimples were conducted. From the obtained results, it had been observed that the warmth transfer coefficient and Nusselt number were high for the copper plate during which the diameter of dimples increases centrally within the direction of flow
