| Abstract: | Combined natural convection and radiation heat transfer in a two dimension emitting and absorbing medium is studied numerically in this paper. A series of numerical models have been proposed,which are vorticity stream function and P-3 method and weighted sum of gray gases model. The effect of radiation on the flow and temperature field distribution,thermal boundary layer and flow boundary layer is discussed. |
