Examination of Thermal Performance for Solar Air Heater with Modified Absorber

Abstract

Everyday sun delivers enormous amount of energy towards earth. Solar energy received by earth in a day is equal to total energy consumed by us in whole year. Plenty of research has been done in utilizing solar energy efficiently. Solar air heater is always a hot topic between the researchers. Different configurations of absorber plate with roughness has been prepared and tested to increase efficiency. In this article, a Computational Fluid Dynamic analysis of solar air heater having triangular shaped bodies place over the absorber plate had been performed. Enhancement in the performance of solar air heater is resulted.
