摘要：
The cumulative wavenumber method for solution of the spectral radiative transfer problems in high temperature gases is extended to account for non-gray walls. The proposed efficient CW-1 method with optimized step-wise constant representation of the wall spectral properties is an attempt to minimize the number of equations requiring solution while preserving reasonable accuracy. The influence of spectral modeling of the non-gray walls on predicted total net radiative flux divergence in the medium and on the wall net radiative fluxes is demonstrated. (C) 2012 Elsevier Ltd.
