The calculation of radiative transfer in a two dimensional enclosure with participating media is based on the Finite volume method. Radiative heat transfer in a black square enclosure with a heated bottom wall in an absorbing, emitting and gray gas medium has been studied. Attention is directed towards the evaluation of radiative incident radiation energy effect with different values of time when energy transport is characterized as a radiant phenomenon. The spatial and angular discretization of two-dimensional geometry is based on finite volume method. The effect of incident radiation energy goes on increasing with time has been concluded by the present study.
