代码说明：

  二维Couette流动是一个不可压缩黏性流动的典型流动，并有解析解，可以用来检验数值算法计算精度和可靠性。对它采用有限体积算法一阶迎风型离散格式进行数值求解。同时，为了初学者入门和练习方便,这里给出了用Fortran77语言编写的计算二维不可压缩黏性流体Couette流动问题计算程序，供大家学习参考。——计算流体力学教程(Couette flow of two-dimensional incompressible viscous flow is a typical flow, and analytical solutions, numerical algorithm can be used to test the accuracy and reliability. It uses the first order upwind finite volume method for numerical solution of discrete format. Meanwhile, for beginner and practice convenience, here are written using Fortran77 calculated two-dimensional incompressible viscous fluid Couette flow problem computer program, for everybody to learn reference.- Computational Fluid Dynamics Course)
