超高速掺气水流中的激波现象——可压缩及不可压缩理论的比较

Shock wave in extra high velocity aerated flow

本文介绍了超高速可压缩掺气水流的均质绝热激波理论和不可压缩急流冲击波理论，并针对明渠边墙突然偏转情形中的超高速掺气水流，对两种理论预测的结果进行了详细比较，二者差异极大．此外，本文还提出了一个简便判据。

The homogeneous adiabatic theory for compressible shock wave in extra high velocity aerated flow and the homogeneous theory for incompressible hydraulic jump and oblique shock wave in supercritical aerated flow are introduced in this paper.The comparison of the predications for the flow in the vicinity of an abrupt wall deflection by compressible and incompressible theory is made and remarkable difference is found.A discriminant for identification of the existence of compressible effect in extra high velocity aerated flow is suggested.
