摘要：

为掌握轨控推进器尾焰的吸收特性，研究了尾焰对太阳红外辐射的吸收问题。在贴体坐标系下，运用有限体积法，建立了尾焰对太阳红外辐射的吸收模型。经过求解，获得受到尾焰吸收后、在尾焰边界处的太阳光谱辐射亮度。比较吸收前和吸收后太阳的光谱辐射亮度，发现：当喷口距离等于0.483m时，在波数1700 cm-1、2155 cm-1、2175 cm-1、2375 cm-1、3700 cm-1和3750 cm-1处，尾焰的吸收率接近于1。此结果对于全面掌握轨控推进器尾焰的吸收特性具有重要的借鉴意义。

Abstract:

In order to know the absorption characteristics of the orbit-control thruster plume, the solar infrared radiation absorbed by the plume was studied. In body-fitted coordinate, the model of the solar radiation absorbed by the plume was founded by using the finite volume method. At the plume boundary, the spectral luminance of the solar radiation which had been absorbed by the plume is obtained by calculating the model. The spectral luminance of the solar radiation absorbed is compared to the spectral luminance without absorption. The result indicates that when the distance between the plume and the nozzle exit is 0.483 m, the plume absorptance equals to one approximately at the wavenumber of 1700 cm-1、2155 cm-1、2175 cm-1、2375 cm-1、3700 cm-1 and 3750 cm-1. The result is very useful to know the absorption characteristics of the orbit-control thruster plume comprehensively.

Key words: plume, absorption, the solar radiation, finite volume method, radiative luminance
