Abstract: The finite-volume method for the radiative heat transfer is applied to linearly anisotropic plane-parallel scattering media.The results are compared with those obtained by the existing exact solutions,the radiation element method and the Monte Carlo method.It is shown that the results obtained by the finite-volume method are reliable.According to the analysis,the effect of the phase functions on the radiative heat transfer has some definite regularity.Furthermore,it is found that the ratio of the dimensionless heat flux in two two-dimension slabs with different scattering phase functions is a monotonous function of the optical thickness.It can be used as a benchmark to verify the results obtained with other methods.
