Abstract

The uniform deterministic discrete method (UDDM) is used to compute the direct exchange areas of zonal analysis in a complex enclosure with participating medium.FOr solving energy matrix equations

the principal variable correction method is adopted

and its principle is described in this paper together with an explanation of its Physical basis.In order to combine the calculations of radiation and convection

a two-level grid is used.The results from this model have shown that a series of calculation methods on radiative heat-exchange in this paper can meet the case of engineering accuracy.
