摘　　要：二维方腔流动是不可压缩黏性的典型流动,可以用来检验各种数值算法计算精度和可靠性,目前尚不能求得它的解析解.基于Matlab编程,采用交错网格MAC算法求解二维方腔流动,计算采用控制容积积分法离散控制方程,对流项和扩散项采用中心差分格式,得到流动达到稳定状态时各物理量的分布.Two-dimensional square cavity flow is a typical incompressible viscous flow, which can be used to test a vari-ety of numerical algorithms for computational accuracy and reliability, yet its analytical solution still cannot be achieved.Based on Matlab programming, the staggered grid MAC algorithm was used to solve two-dimensional square cavity flow.Control volume integral method was used to discrete the control equations for calculation. Central difference scheme wasapplied for convection and diffusion terms. In the end, the flow simulation results of each physical quantity distribution insteady state were obtained.
