摘　　要：很多的实际水流问题可近似地用势流理论来求解,常采用的计算方法是有限单元法,通常用FORTRAN、C语言等编程求解,但计算程序比较复杂。本文介绍了MATLAB的偏微分方程工具箱(PDEToolbox),并用于圆柱绕流计算及图形显示计算结果。计算表明,用MATLAB的PDEToolbox求解平面势流便捷高效,值得研究应用。In practical engineering, many problems of water flow belong to potential flow approximately. FORTRAN,C language are usually used to compute it.This paper presents PDE(Partial Differential Equation)Toolbox of MATLAB and apply it to compute cylinder circumambient flow. The result of the application example shows that the calculating of planar potential flow with PDE Toolbox of MATLAB is simple and convenient.
