Summary:A spatial-multiblock procedure for radiation heat transfer is presented in this article. The proposed procedure is applicable to isothermal or nonisothermal, absorbing, emitting and scattering or transparent media with black or reflecting walls. Although not shown in this article, the procedure is also applicable to nongray conditions. The proposed procedure can be used with the discrete-ordinates method and the finite-volume method. The heat transfer rate, net radiant power, and other full-range and half-range moments are conserved between spatial blocks by the proposed procedure. The utilities of the proposed procedure art shown using four sample problems. The solutions indicate that the multiblock procedure can reproduce the results of a single-block procedure even when very coarse spatial grids are used in the multiblock procedure.
