These flows are obtained with a simple numerical method based on a fixed point iterative process to solve the nonlinear elliptic system that results once a time discretization is performed.Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.6 pagesPDFenUniversity of PretoriaNatural convectionVelocity-vorticity formulation2D natural convectionBoussinessq approximationNavier stokes equationsFixed point iterative processNonliner elliptic systemViscous incompressible flowHeat transferPresentation
