报告摘要
This talk is concerned with the monotonicity of differential pressure and the geometric property of free boundary to compressible subsonic jet flows. We prove that the differential pressure is strictly monotonic with respect to incoming mass flux. If the nozzle wall is convex, we will prove that the fluid speed takes minimum on the free boundary and establish the concavity of free boundary. Finally, the optimal regularity of free boundary at detachment is obtained.
