A Review on Roughened Solar Air Heater for Heat Transfer and Thermal Efficiency
Abstract: The use of artificial roughness on the absorber plate is the most effective technique to enhance the thermal performance of solar air heaters. Experimental investigation of distinct roughness geometries shows that the enhancement in the rate of heat transfer is accompanied by considerable rise in temperature. In this paper some distinguished roughness geometries have been compared on the basis of heat transfer rate and thermal performance. The objective of this …
