This paper presents a comparative study of several numerical methods which have been proposed for solving two-dimensional incompressible viscous flows. These methods are the vorticity stream function method, the MAC method on a staggered grid, Chorin's artificial compressibility method with/without convergence acceleration and Abdallah's method on a non-staggered grid. The steady laminar flow in a square driven cavity and a two-dimensional channel with 90° bend are chosen as test problems. It is found that all of the methods give practically the same computed results except for the pressure distributions in the two-dimensional channel problem obtained by the vorticity stream function method. The numerical experiments show that the artificial compressibility method with convergence acceleration has the best convergence rate.
