带有扰动项的3D Euler方程

The 3-D Euler Equations with a Disturbing Term

本文主要研究了加一项扰动项εu后的三维欧拉方程情况。通过借助于柱坐标变换,讨论在有旋的情形下,方程组有轴对称解的条件,并得到一个新的结果。

In this paper, the three-dimessional Euler equations with a disturbing term have mainly been studied. By means of the cylindrical coordinate transformation, the condition of the axisymmetric solution has been discussed under the swirl situation and a new result has been obtained.
