楔体绕流中斜向shock waves的解析表征

Analytic characterization of oblique shock waves in flows around wedges

Hady K. Joumaa

摘要:

本文研究了三角形楔体的可压缩绕流问题,在三角形楔体中形成斜激波。我们报告的新的分析解决方案的最大楔角的评价超过冲击波脱离楔,以促进形成弓形激波。此外,确定了通过斜激波的气流变为音速的极限线,从而给出了相应激波角的解析表征。

英文摘要:

We consider the compressible flow around triangular wedges in which oblique shock waves are formed. We report on the novel analytic solution regarding the evaluation of the maximum wedge angle beyond which the shock wave detaches from the wedge to promote the formation of a bow shock. In addition, the limit line at which the flow past the oblique shock becomes sonic is determined whereby an analytic characterization for the corresponding shock angle is presented.
