Abstract

A new algorithm, the discrete ordinates radiation element method (DOREM), for modeling radiative heat transfer in inhomogeneous three-dimensional participating media is described. The DOREM uses advantages of the both the radiation element method (REM) and the discrete ordinates method. Benchmark comparisons are conducted against several radiation models. The DOREM successfully implements radiative heat transfer simulations precisely, since false scattering never occurs. The DOREM has advantages of computational speed against Monte Carlo, and the CPU time and the memory size of the DOREM are 82 times faster and 767 times smaller at the maximum than that of the REM.
