| 摘 要： | 本文直接从音速线出发计算了一个旋成体跨音速绕流超音速泡中的特征线网。提出了从音速线开拓到一条超音速线的方法,计算了无旋轴对称流的特征线网,发现其特点是不能跨越对称轴线,并对其原因作了初步的讨论。本文的计算结果可应用于物面修形。

| Abstract: | A characteristic net in the supersonic bubble, which is originated from the transonic flow around a body of revolution, was constructed directely starting from the sonic line. A method developing a supersonic line (but not an isovelocity line )from a sonic line was presented. A characteristic net in the irrotational axisymmetric flow was calculated. Is was found that the net is impossible to spread over the symmetric axis and the cause was preliminarily discussed. The calculated results of present paper can be applied to the surface revision. |
