摘要
为了给长尾喷管热防护结构设计提供热边界条件 ,从轴对称二维雷诺平均N S方程出发 ,采用分区算法和有限容积法计算了长尾喷管中的湍流流动 ,分析了流场的结构特性 ,得出了长尾喷管中燃气温度、压强和马赫数分布的某些规律以及燃气温度沿壁面的分布。
Based on axisymmetric two-dimensional N-S equation, finite volume method and multiblock algorithm were used to study turbulent flow for a tail-pipe nozzle,providing thermal environment for the design of anti-thermal construct. The flow field was investigated and some properties of the distribution of temperature, pressure and Mach number of gas in nozzle and temperature of gas along the wall were obtained. From the calculation and analysis, some suggestions were put forward for the design of anti-thermal construct.
