Based on SIMPLE algorithm, Navier-Stokes equations under threedimensional cylindrical coordinates were solved by using the special mesh method to eliminate the singularity at the axis, thereby the computation of three-dimensional turbulent fluid flow in cylindrical reactors can be performed on personal computer and the program developed can be applied in many fields.
本文以ＳＩＭＰＬＥ算法为基础并采用特殊网格方法消除柱坐标系极点奇异性，通过对Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程进行数值求解实现了圆筒形反应器内三维湍流流动的计算。
