摘要
The effect of thermal radiation within a porous medium while incorporating local thermal nonequilibrium (LTNE) is investigated in this work, with specific application to solar air receivers. It is shown that the radiation effect is significant. The temperature distributions for both solid and fluid phases are affected by conduction-radiation parameter N, the ratio of solid to fluid phase conductivities zeta, and the interphase convection parameter H. The limiting interactions between conduction and thermal radiation incorporating convection are revealed. The impact of conduction and convection versus radiation is systematically analyzed in this work and displayed through a number of contour maps.
