Abstract:
This paper reports an extension of the theoretical findings on the relatively new concept for radiative energy recovery system using porous media. The basic high-temperature flow system is considered in which the hot radiating gas flows through a homogeneous porous layer. The porous layer, in addition to convective heat exchange with the gas, can absorb, emit and scatter thermal radiation. It is desired to have a large amount of radiative heat flux from the porous layer to the upstream direction ( toward the system ). The two-flux radiation model is used to obtain the distribution of radiative heat flux in the porous media. The numerical solution of the coupled energy equations for the gas and porous layer in steady condition, are obtained using Runge Kutta method. The crucial influence of gas radiation effect on the system performance is thoroughly
explored.
