Abstract

The prime objective of this research work is to minimize the consumption of conventional energy sources. Solar air heater is device, which has the great potential to harness the solar energy for low temperature applications such as space heating, drying agriculture product and industrial applications. An experimentation performed on impinging jet solar air heater for thermal investigation. Solar air heater contains a glass cover, flat jet plate and a corrugated absorber plate. In this experimental investigation, air enters in first channel (between glass cover and transparent jet plate) and through jet holes, air enters in second channel (between transparent jet plate). Because of jet impingement, thinning of the boundary layer takes place, which increases the heat transfer from hot absorber plate. Heat losses are minimized by using insulation and jet impingement from upper side of the absorber plate. The maximum outlet air temperature about 38 oC obtained at mass flow rate of 0.01kg/s.
