我们提出了一种算法，提供了一个频域解的辐射传输方程（ERT）的非均匀介质的任意形状。虽然ERT比扩散方程更准确，但迄今为止还没有广泛采用的频域情况的ERT代码。在这项工作中，ERT离散的离散纵坐标和有限体积法相结合。两个数值模拟。(C)2004年美国光学学会。
We present an algorithm that provides a frequency-domain solution of the equation of radiative transfer (ERT) for heterogeneous media of arbitrary shape. Although an ERT is more accurate than a diffusion equation, no ERT code for the widely employed frequency-domain case has been developed to date. In this work the ERT is discretized by a combination of discrete-ordinate and finite-volume methods. Two numerical simulations are presented. (C) 2004 Optical Society of America.
