An algorithm for coupled solving 2D Navier-Stokes equations in the stream function ~-vorticity oJ variables is presented. Lid driven cavity flow is computed as a test example. Implicit difference schemes on uniform grids are used for discretizing the unsteady Navier-Stokes equations. An iterative me
