摘要/Abstract

摘要： 将描述非灰气体辐射特性的指数宽带模型引入均匀离散射线法,推导了非灰气体参与介质条件下,辐射全交换面积的计算式,并计算了二维封闭体系的辐射全交换面积。结果表明,均匀离散射线法可用于模拟非灰气体中的辐射换热问题。

关键词: 非灰气体, 辐射全交换面积, Monte Carol法

Abstract: The uniform deterministic discrete emission method and wide band model are combined to calculate the total radiant exchange areas for a two dimensional enclosure filled with nongray gas.The results show that the uniform discrete deterministic emission method can be used to a nongray medium.At the same samples the uniform discrete deterministic emission method is better than Monte Carlo method.

Key words: nongray gas, radiant total exchange areas, Monte Carlo method
