二维范德瓦尔斯气体磁流体绕凸拐角的超声流动

Abstract

Abstract:

In this paper, we study the supersonic flow of two-dimensional isentropic van der Waals magnetic fluid around convex corners. According to the value of the specific volume of the incoming flow, the flow at the convex corner is discussed by classification. It is shown that the supersonic incoming flow can turn the convex corner by a centered rarefaction wave, a sonic shock or a composite wave of them, and the critical angle of the corner corresponding to the appearance of the vacuum phenomenon is obtained.

Key words: Convex corner, Van der Waals gas, Composite wave, Vacuum.
