摘要: <正> 引言 从压缩拐角分离流动的试验及数值计算出发,建立起一个实用范围较广精度较高的工程估算程序,方便快速地估算出压缩拐角分离区和再附区的峰值压力、峰值热流;分离区和再附点位置;分离区长度等。这是气动设计部门关注的课题。这些工作是在文献(3,4)中的经验公式的基础上,按照分离流动流谱,分区进行迭代修正计算,对二维情况给出了完整

Abstract: An iterative correction method is presented in this paper for predicting the pressure and the heat rate in the separated and reattached regions in a compressible corner. The metho’d is constructed based on the basic separated flow patterns, in conjunction with empirical formulas. For the two-dimensional compressible corner, good agreement is obtained for the pressure and heat rate with the experimental data.
