报告摘要:In this talk, I will report our recent study on the supersonic-sonic solutions for the three-dimensional steady axisymmetric Euler equations. Given a velocity distribution on a streamline, we construct a small smooth supersonic-sonic patch for the isentropic irrotational flow, which can be regarded as the region near the upstream vertex of a supersonic bubble. The uniform regularity of solution up to the sonic curve and the regularity of the sonic sonic are also discussed.
