Abstract : In the present study, the heat transfer enhancement of laminar air flows over concave and ribbed surfaces have been investigated experimentally in a wind tunnel. The experiments were performed over a flat plate, a curved surface with a radius of 2.54 m in concave curvatures and a ribbed surface has a rib aspect ratio (the ratio of the rib width to the rib height)of 1.2 for the free stream velocity of 2 m/s. A constant-temperature hot wire anemometer and copper-constant thermocouples were used to the velocity and temperature measurements, respectively. The results show that the heat transfer rates are increased up to 60% by the concave and 175% by the ribbed surface comparing to the flat plate. It is noted that ribs give the higher heat transfer augmentation than concave surface. Keywords — Heat Transfer Enhancement, Laminar Flow, Ribbed Surface, Concave Surface.
