摘要

摘要: 耦合求解流场、组分浓度场、基于SNBCK模型的气体辐射传输/能量方程以求准确模拟飞行器排气系统气动热力及红外特性.窄带模型参数由HITEMP逐线计算数据库计算得到.通过CO₂4.3μm波段吸收率计算,圆柱炉膛辐射换热特性计算两个算例验证了所采用程序求解辐射传输/能量方程的准确性.最后计算了两种二元喷管的红外特性,结果表明大宽高比二元喷管地面和空中状态红外辐射特性差异巨大.

Abstract: The coupled calculations for flow fluid field, species concentration field and gas radiation transfer /energy equations based on SNBCK model were employed to simulate accurately the aerothermodynamic and infrared characteristics of the aircraft exhaust system. The parameters of narrow-band model were evaluated by HITEMP line-by-line database. Two calculating cases, the computation of carbon dioxide absorptivity at 4.3 micron band and the radiation heat transfer evaluation of the cylindrical furnace, respectively proved the accuracy of using this method to calculate radiation transfer/energy equations. Finally, the infrared characteristics of two two-dimensional nozzles were calculated, and the results show the great differences of infrared characteristic for high width-height ratio 2-dimentional nozzle between ground and high altitude state.
