Abstract: The idea of introducing artificial roughness on absorber plate to improve the thermal performance of a solar air heater is very common now days. The technique uses the concept of providing artificial roughness by imbedded element in the absorber plate of the heater. Diagonally chamfered cuboids have been used as roughness element in the current stu... Show More
