Document Type: JOURNAL ARTICLE Most documents available from AIAA Technical Library J ourn a1 A n n o uncement: IAA8507 An iterative method is proposed for the joint solution of implicit difference equations approximating the energy equation and the equation of nonstationary spectral radiation transfer with allowance for isotropic scattering. In the case of an optically thick medium, it is sufficient to examine radiation transfer in the diffusion approximation. In the 'gray' linear case, it is shown that the proposed iterative procedure converges at a geometric- progression rate. The method used is pertinent to the mathematica1 modeling of high-temperature processes. (L.M.)
