Abstract

Enhancement of heat transfer rate is important factor in order to improve performance solar air heater. This enhancement is possible by means of incorporating artificial roughness. The effect of artificial roughness is studied using CFD. The analysis software used is ANSYS CFX. Artificial roughness is used in one side wall of solar air heater absorber plate to break laminar boundary sub layer. It enhances rate of heat transfer from the absorber plate to flow of air stream. The artificial roughness is varied with different (P/E) ratio at various Reynolds number. Outlet temperature, heat transfer rate and Nusselt number is computed.
