一种新的CO_2高温辐射特性窄谱带模型参数计算方法

A NEW METHOD OF CALCULATING HIGH TEMPERATURE RADIATIVE PROPERTY PARAMETERS OF NARROW-BAND MODEL FOR CO_2

本文以美国空军地球物理实验室最新的高分辨率高温燃气光谱数据库ＨＩＴＥＭＰ（序列号：３１５３）为基础，在３００～ ３０００ Ｋ的温度范围内，计算了二氧化碳的谱带模型参数 κ，β，得到了比 １９７３年 ＮＡＳＡ发布的数据更新、更详细的数据。同时以本文的模型参数为基础，采用统计谱带模型计算了各个谱带各种光学路径下的发射率、穿透率，其结果与实验、逐线计算值（Ｌｉｎｅ－ｂｙ－Ｌｉｎｅ）符合很好。

A new method of calculating narrow band model parameters of CO2 is present. And the up-to-date high resolution and high temperature flame gas spectral databas-HITEMP (serial number: 3153) is used for evaluation model parameters and Line-by-Line benchmark solution. From 300 K to 3000 K, parameters such as κ,β are achieved, which are more updated and more detailed than NASA's data in 1973. Based on these parameters, the emissivities and transmissivitie are evaluated under different temperature, pressure and o...
