报告摘要:  In this talk, we discuss the incompressible steady Euler flows in nozzles with stagnation, in particular, the ones with Poiseuille flows at the upstream. We first present a Liouville type theorem on Poiseuille flows for steady Euler system in an infinitely long strip. With the aid of the delicate analysis on the energy minimizers, we show the existence of steady Euler flows with Poiseuille flows at the upstream. In particular, we observe the possible free boundary phenomena because of stagnation. This is a joint work with Professor Congming Li and Professor Chunjing Xie.
