Abstract

The term solar air heating is a technology in which the radiant energy emitted by the sun is captured in an absorber and is used for space heating and the device used is Solar Air Heater. The Performance of Solar Air Heater found to be low due to Low Heat Transfer Coefficient between Absorber Plate and Air. When Air Passes through Solar Air Heater Duct, Laminar Sub Layer is created on Absorber Plate, Which Reduce Heat Transfer between Absorber Plate and Air. Improvement in the thermal performance of a solar air heater can be done by enhancing the heat absorbing and transfer capacity of absorber plate. Providing an artificial roughness on a heat transferring surface (Absorber plate) is an effective heat transfer technique to enhance the rate of heat transfer to flow of air. So, the different types of artificial roughness viz. Horizontal, Zig-Zag and V-shape on Absorber Plate is used to break this Laminar Sub layer.
