The flows are obtained with a simple numerical method based on a fixed point iterative process to solve the nonlinear elliptic system that results after time discretization; the iterative process leads to the solution of uncoupled, well­-conditioned, symmetric linear elliptic problems for which efficient solvers exist regardless of the space discretization. The numerical experiments are given for the Taylor vortex and the driven cavity problems.4 pagesPDFenUniversity of PretoriaVelocity-vorticity variablesTaylor vortex problemDriven cavity problemFixed point iterative processPresentation
