摘要：
The 2D unsteady Navier-Stokes equations in its velocity-vorticity formulation, after time discretization, leads to a nonlinear elliptic system which may be solved by iterative methods; however, decoupling the nonlinear vorticity equation from the vorticity in the velocity equations by linear interpolation, a direct method is applied, allowing the vorticity equation to be linear. Steady state convergent flows from the un-regularized unit driven cavity problem, which causes recirculation because of the nonzero boundary condition on the top wall, are reported for Reynolds numbers Re, 400 <= Re <= 4000.
