摘要/Abstract

摘要： 用宽带及其修正模型模拟非灰介质的辐射特性,并将它用于区域法模型,计算了非灰气体介质中表面-表面之间的辐射直接交换面积。结果表明:修正的宽带模型对气体辐射特性的描述是比较准确的,且它易于与区域法相结合。

关键词: 宽带模型, 辐射直接交换面积, 区域法数学模型

Abstract: Wide band mold and its modification are used to simulate the radiative properties of non-gray gases, and they are combined in zone method to calculate the surface surface radiative direct exchange areas for a non gray medium. Results show that the modified wide band model can successfully describe the properties of non gray gases, and can be easily combined with zone method.

Key words: wide band model, radiative direct exchange areas, zone method
