摘要

用直角坐标系下有限体积法研究了二维矩形介质内辐射传递，散射相函数采用Legendre多项式展开.与其他文献的计算结果比较证明了本文有限体积法模型是可靠的.研究表明，相函数及反照率等对温度分布有影响.比较了线性各向异性散射与各向同性散射矩形介质内的温度场，对于不同的误差要求对应存在一个衰减系数及反照率取值区域，在该区域内选取物性参数则可以将线性各向异性散射简化处理为各向同性散射，从而方便了计算.

Abstract

The finite-volume method for radiative transfer is applied to two-dimensional rectangular enclosures.The results are compared with those obtained by the existing solutions.It shows that the result obtained by finite-volume software is reliable.According to the analysis，different phase function and scattering albedo have effects on the temperature profile.Meanwhile

the temperature distributions in the two-dimensional rectangular media with linear anisotropic scattering and isotropic scattering phase function are calculated respectively.The results show that there is a definite zone for the different extinction coefficient and scattering albedo

which satisfies the given precision.Therefore

when the two parameters are chosen in this zone

the anisotropic scattering media can be simplified to isotropic scattering media

and it makes the model easier.
