利用Ｍｏｎｔｅ－Ｃａｒｌｏ法和Ｚｏｎｅ法结合Ｅｄｗａｒｄｓ提出的指数宽带模型提出了对非灰气体辐射传热进行分析的一种简化算法．分析对象采用一维平板系统，首先验证了用Ｅｄｗａｒｄｓ宽带模型计算实际气体辐射特性的准确性，然后对给定平板温度下处于热平衡状态时的温度分布进行计算，并与灰气体处理时的计算结果作了对照，得出了相应结论． Using Monte-Carlo method and Zone method combined with the exponential broadband model proposed by Edwards, a simplified algorithm for analyzing radiative heat transfer of non-ash gas is proposed. The analysis object uses a one-dimensional slab system. First, it verifies the accuracy of Edwards’s broadband model to calculate the actual gas radiation characteristics. Then, the temperature distribution at a given slab temperature in thermal equilibrium is calculated. Compared with the calculation results Made a comparison, reached the corresponding conclusion.
