锥体高超声速尾流辐射特性

应用显式有限差分法求解了轴对称尾流边界层方程,求出高超声速锥体尾流化学非平衡流场。在求得温度、速度、密度和粒子浓度场的二维分布的同时,详细求解尾流中各种粒子的辐射强度和辐射量的二维分布。

RADIATIVE CHARACTERISTICS OF HYPERSONIC CONE WAKE

A finite explicit difference method is applied to the axisymmetric boundary layer equations of hypersonic air wake in chemical nonequlibrium behind hypersonic cone. Two-dimensional distribution of temperature, density, concentration and electronic density are obtaineed. Simultaneously, the detailed numerical calculation of radiative intensity and radiative quantity are completed for the princ-ipal species which are the source of the wake radiation. We find that the most part of the raditions from the wake is NO infrared within the calculated range of this paper.
