Abstract

In the present paper experimental study has been performed to investigate heat transfer under row of jets impinging to an asymmetric concave surface. In this regard two asymmetric concave surface with curvature radiuses of (8, 12) and (8, 24) cm have been considered. Constant heat flux of 2500 W/m2 is applied on the concave surface using a silicon rubber heater mat. In the steady-state condition the temperature distribution of the concave surface is measured with an infrared camera. The studies of asymmetric flow and heat transfer in asymmetric surfaces have been carried out for three Reynolds numbers of 10000, 20000 and 30000. Results show that, the concave surface with lower curvature radius has more values of Nusselt number distributions. The present results confirm that the Nusselt distribution is asymmetry along the S axis. In the axial direction, symmetry distribution is observed for Nusselt number.
