摘要：In this talk, we introduce steady two-dimensional inviscid, incompressible jet flows with gravity and constant vorticity. The main results read that given a mass flux, atmosphere pressure $p_{atm}$ and a vorticity of the incoming flows in the inlet of the nozzle, we establish the existence of the incompressible jet flows with gravity and vorticity in an infinitely long channel. Furthermore, there exists a smooth free surface. The free surface becomes to be horizontal in downstream and initiates at the endpoint of the nozzle smoothly.
