摘要
建立火箭发动机尾焰红外辐射传输的有限体积离散模型,采用逐线积分方法计算气体光谱吸收系数,计算不同组分的尾焰红外辐射特性,得到组分分布对液体火箭发动机尾焰红外辐射特性的影响规律。
An finite volume model was established to calculate the spectral absorption coefficients of the components by line-by-line method.The infrared radiation characteristics from rocket exhaust plume are obtained.Different distributions of the components are considered to analyze the influence on the infrared radiation characteristics.Some interesting conclusions are finally achieved.
