The objective of this study is to investigate heat transfer and fluid flow characteristics of spandrel panel. Spandrel panel has been using as a house wall which is a collector of solar thermal energy. The spandrel panel is a construction steel board having cyclic grooved pattern. In order to improve performance of the spandrel panel as a heat collector, it is necessary to improve an efficiency of heat transfer from the spandrel wall to the air in the panel. Therefore, the method for enhancing heat transfer such as inserting the porous material into flow channel of the spandrel panel is expected an effect of expansion of area which generates heat transfer and thermal radiation. We have carried out a numerical analysis of natural convection in spandrel panel using the commercial CFD code. This paper describes the heat transfer and fluid flow characteristics of inside channel having grooved pattern when inserting the porous material into flow channel. From the results, it was found that the gas temperature was increased by inserting the porous material but the amount of heat removed was decreased by inserting the porous material.
