摘要: 采用有限体积法研究了一维线性各向异性散射介质内散射相函数对辐射传递的影响规律.经与理论解、辐射元法、蒙特卡洛法计算结果比较表明,有限体积法的计算结果更可靠,且不同散射相函数的辐射换热系统中,其无因次热流之比与光学厚度之间存在某种单调变化的函数关系,利用该函数关系可以检验模型的准确度.

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.

Key words: radiative heat transfer, finite volume method, anisotropic scattering, scattering phase function
