Performance Analysis of a Double Pass Solar Air Thermal Collector with Porous Media Using Lava Rock

Abstract: This paper investigates double-pass solar air thermal collectors with lava rock as the porous media. The addition of lava rock serves as short-term sensible thermal storage for a solar drying system. It also enhances the convective heat transfer rate to the airflow due to an increased heat transfer area and increased turbulence in the air channel. A mathematical model was developed based on energy balance equations and was numerically solved in MATLAB. The collector’s thermal performance was studied at various… Show more

“…Nevertheless, air solar collector has a low heat transfer rate due to its low thermal conductivity properties and higher volume of air per unit area is required [5]. Hence, in order to address this issue, a double pass configuration can enhance the convective heat transfer that occurs within the collector due to an increase heat transfer area [6], [7].…”
