Performance analysis of single‐pass solar air heater thermal collector with adding porous media and finned plate

Abstract

AbstractThe recent study encompasses a practical inspect on adding porous material above absorber flat plate having fins to improve the effectiveness of solar air heater (SAH) collector along with forced air circulation process. The efficiency of the altered model and conventional SAH system is compared at the same time to display the impacts of adding porous material. The model that used porous material is called Model‐2, whereas the conventional SAH is called Model‐1. The measuring data is collected in January 2021 in Iraq (Mosul city). Outcomes emphasize that the effectiveness of altered model is better than traditional model by 7% for all air mass flow rates values. The highest efficiency is obtained equal 67% for Model‐2 and 60% for Model‐1 for mass flow rate 0.02 kg/s. For all mass flow rate values, a substantially change in temperature is observed in altered system as compared to traditional system, where the exhaust temperature of Model‐2 is higher than Model‐1. The improvement in the effectiveness of Model‐2 demonstrates that the employ of porous material has an extreme action on the heat exchange and subsequently heat transfer rate.
