The initiation point is not fixed on the focusing point but varies with the incident shockMachnumber.
爆轰波爆点位置在对称轴上并不是固定的点，而是随着初始激波马赫数的变化而发生移动；

The computational results are in a good agreement well with the experimental data of Machnumber before the shock wave, separation and reattachment positions.
数值模拟结果，在激波强度、分离点位置和再附点位置等方面，与实验结果吻合较好。

This paper presents the surface characteristics of the inter-action between shock wave and turbulent boundary layer induced by sharp fin with emphasis on Machnumber effects.
