A review on Types of Roughness Element Used in Solar Air Heater to Enhance Heat Transfer Coefficient
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
Solar air heaters provides the efficient use of solar energy, which uses the absorber plate to absorb the incoming solar radiations, converting it to thermal energy at its surface, and transferring the thermal energy to the fluid flowing through the collector. The most common and effective way to improve the performance of the solar air heater is to provide artificial roughness elements on the underside of the absorber plate. For the enhancement of rate of heat transfer of flowing air in the duct of a solar air heater, by applying an artificial roughness on its surface is one of the very effective technique of solar air heater absorber plate, till now numbers of geometries of roughness element has been investigated and their effect on enhancement of heat transfer has been carried out. This paper is an attempt has been made to classify and review various study of roughness geometries used for creating artificial roughness.
