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
Introduction Starting from the experiment and numerical calculation of the separation flow at the compression corner, an engineering estimation program with a wide range of practical scope and high accuracy is established to estimate the peak pressure and peak heat flux in the corner separation zone and the reattachment zone conveniently and quickly. The separation zone And re-attachment point location; separation zone length and so on. This is the topic of aerodynamic design department. These works are based on the empirical formula (3, 4), according to the separation of the flow field spectrum, sub-area iterative correction calculation, given two-dimensional situation is complete
