Solar air heater is a most popular device in the space heating and industrial processes applications. But solar air heater has lower heat-transfer coefficient between the absorber plate and the air stream, which results in a lower thermal efficiency of the heater. The solar air heaters efficiency can be affected by various parameters such as collector length, number of channels, depth of channels, type of absorber plate, number and material of glass covers, air inlet temperature and air velocity. Comparative study of double pass solar air heater with fins, baffles and porous material’s effect has been carried out in this research study. Also, mass flow rate at the outlet of the double pass solar air heater in the metallic wiry sponge is significantly improve as compared to the other double pass solar air heater. So that, the maximum efficiency as been gained in the double pass solar air heater with metallic wiry sponge as compared to the other.
