Abstract
Solar Air Heater (SAH) is device which is mostly used to heat air in cold climates .That heated air has lots of applications including warming building, agricultural producer etc. In present work, an experiment of work has been done to see how a Solar Air Heater (SAH) can be made more effective. This study examines the thermal performance of a Solar Air Heater (SAH) with a W- discrete, V discrete, and a plain absorber plate at various mass flow rates. Outlet air temperature and thermal efficiency were two experimental outputs that were evaluated to find the performance. At a mass flow rate of 0.049 kgs, the W discrete absorber plate SAH was found to have a maximum thermal efficiency of 83%, which is respectively 39.83% and 30.16% greater than the W discrete and V- discrete SAH. This study showed that for the parameter under consideration, flow configurations with W discrete and V- discrete solar plate outperform and smooth plate SAH in terms of thermal performance. The angle at which air strike V discrete absorber plate is 60, where as the air has to strike two 60 angled plate for the case W-discrete absorber plate.As the friction factor has high value for two 60in (W-discrete solar plate).The thermal performance of absorber plate with W- discrete is high.
