摘要：
A numerical method is proposed for the transport of infrared radiation in participating medium. The method is implemented using the Finite Volume Method (FVM) for solving the radiative transfer equation (RTE), and Mie theory for computing the absorption and scattering characteristics of the medium. The advantages of the method reflected in two aspects. On the one hand, the radiative characteristics is got from a data base established in advance using Mie theory, on the other hand, the scattering phase function is simplified by distinguishing the "forward average scattering" and "other directional average scattering". Both the two procedures yield significant computational savings with little loss in accuracy for predictions of spectral and total transmission.
