摘要:
本文的主要内容是研究半无穷长对称管道中不可压缩、无粘带重力的喷流的适定性. 主要结论是如果在管道入口给定流体的一个质量通量,我们能够建立半无穷长管道中不可压缩带重力喷流问题的存在性和唯一性,该喷流问题还有连接下管道壁边界点的光滑自由边界.
Abstract:
The main object of this paper is to investigate the well-posedness theory of the incompressible inviscid jet flow with gravity in an semi-infinitely long symmetric nozzle. The main results read that given a mass flux in the inlet of the nozzle,we established the existence and the uniqueness of the incompressible jet flow problem with gravity in an semi-infinitely long symmetric nozzle,which contain a smooth free surface detaching at the boundary point of the lower nozzle wall.
