一维可压缩黏性流动是气体动力学中最经典的黏性流动问题，对它采用迎风型 差分算法进行数值求解。-One-dimensional viscous compressible gas flow dynamics in the most classical viscous flow problems, it uses upwind difference method for numerical solving.

二维 流动问题是有解析解的二维不可压缩黏性流动。对它采用 算法和 压力迭代解法进行数值求解。-Two-dimensional flow problem is a two-dimensional analytical solution of incompressible viscous flows. It uses an iterative solution algorithms and numerical solution pressure.

二维方腔流动问题是一个不可压缩黏性流动中典型流动。虽然目前尚不能求得它的解析解，但是它常被用来作为检验各种数值算法计算精度和可靠性的算例。文献中几乎大多数算法都对它进行过计算。在本算例中采用有限体积算法三阶迎风型 离散格式对它进行数值求解。-The problem is two-dimensional square cavity flow incompressible viscous flow in a typical flow. Although it is still analytic so
