摘要
本文根据从无穷远处均匀流来的粘性流体,绕球心位于原点的圆球流动的时候,其流场具有明显的轴对称性这一特点,通过引入流函数的办法,给出了采用柱坐标时小雷诺数流体绕圆球流动问题的轴对称解.
This paper is based on the feature that the flow field is obviously cy- lindrically symmetrical when a viscous fluid homogeneously flows from infi- nity and round a sphere whose center is at the origin of a cylindrical coordinates.By means of the introduction of a flow function,the article gives the cylindrical solution of a small Reynolds number fluid.
