Abstract—Over the past couple of years the use of concavities or dimples to enhance the heat transfer has been reported by several researchers. This work deals with experimental investigation of the forced convection heat transfer over circular dimpled surfaces. The various heat transfer parameters considered for study are Nusselt number, heat transfer coefficient, heat transferrate andReynolds Number. From the obtained results, novel conclusion for thedesign of compactheat exchangercan be drawn (Katkhaw, 2014).

Index Terms—Forced convection, Dimples, Heat transfer augmentation, Compactheat exchanger
