This paper describes conjugate radiation-convection-conduction simulation of a porous solar receiver irradiated by beam-down concentrated light. Simulation was made for three cases where cell sizes and porosity were changed in each of two steps. It was demonstrated that receiver efficiency increased when cell size decreases and porosity increases. Heat transfer losses were analyzed to probe mechanisms of receiver efficiency enhancement. It was found that the thermal radiation losses were attenuated when cell size decreases or porosity increases. The attenuation of thermal radiation increased convection heat transfer by air stream to enhance receiver efficiency.
