报告简介:
In this talk, we focus on the hypersonic limit of two-dimensional steady non-isentropic compressible Euler flows passing a straight wedge, in which the Mach number goes to infinity. A form of the Euler equations, which is valid if the unknowns are measures, is proposed, and a measure solution containing Dirac measures supported on the surface of the wedge is constructed. This justified the Newton theory of hypersonic flow passing obstacles in the case of two-dimensional straight wedges. The talk is based on joint works with Prof. Hairong Yuan, Prof. Aifang Qu.
