| 摘 要： | 本文从处理辐射传热的基本理论出发，给出了一个包含与辐射发射随机方向性有关的比热流参数的新热流模型。该模型克服了原热流模型在理论简化上的缺陷，能够更好地反映炉内的实际情况。同时给出了用Ｍｏｎｔｅ－Ｃａｒｌｏ方法求解比热流参数的计算程序。最后用该模型求解了实验室用马弗炉内的温度分布，同时用原热流法对该高温炉的温度分布进行了计算，与实验结果相比较，新热流方程明显优于原热流方程。

| Abstract: | In this paper, based on the fundamental theory of radiative heat transfer, a new heat flux mathematical model has been given, that contains a specific heat flux parameter relating to the directions of radiative random emission. In the meantime, it has been given that the program of calculating the heat flux parameter with Monte-Carlo method. Finally, using two kinds of heat flux models, the temperature has been calculated in a muffle furnace. Comparing the measured results,the model is better than the old method. |
