Modeling and Simulation of Double-Pass Flat Plate Solar Air Heater Without Porous Media

Abstract

The double-pass solar collector with porous media in the lower channel provides a higher outlet temperature compared to the conventional double-pass collector without porous media. Therefore, the thermal efficiency of the solar collector is higher. A theoretical model has been developed for the double-pass solar collector. The porous media has been inserted to increase heat transfer, area density and the total heat transfer rate. Comparisons of the theoretical and the experimental results have been conducted. Such comparisons include the outlet temperatures and thermal efficiencies of the solar collector for various design and operating conditions. The relationships include the effect of changes in upper and lower channel depth on the thermal efficiency without porous media. Moreover, the effects of mass flow rate, solar radiation, and temperature rises on the thermal efficiency of the double-pass solar collector have been studied. The study concluded that the absence of porous media in the second channel decreases the outlet temperature, therefore reduces the thermal efficiency of the systems.
