Abstract

This paper is devoted to the study of the shape of the free boundary for a three-dimensional axisymmetric incompressible impinging jet. To be more precise, we will show that the free boundary is convex to the fluid, provided that the uneven ground is concave to the fluid.

轴对称不可压缩冲击射流自由边界的凹凸性

本文研究了三维轴对称不可压缩冲击射流的自由边界形状。更精确地说，我们将证明自由边界对流体是凸的，假设不平坦的地面对流体是凹的。

期刊介绍： Acta Mathematica Scientia was founded by Prof. Li Guoping (Lee Kwok Ping) in April 1981. The aim of Acta Mathematica Scientia is to present to the specialized readers important new achievements in the areas of mathematical sciences. The journal considers for publication of original research papers in all areas related to the frontier branches of mathematics with other science and technology.
