A second order splitting algorithm for thermallydriven flowproblems

A splitting technique for solutions of the NavierStokes and the energy equations, in Boussinesq approximately, is presented. The equations are first integrated in time using a splitting procedure and then discretized spatially by means of a highorder spectral element method. The whole technique is v...

Zusammenfassung:A splitting technique for solutions of the NavierStokes and the energy equations, in Boussinesq approximately, is presented. The equations are first integrated in time using a splitting procedure and then discretized spatially by means of a highorder spectral element method. The whole technique is validated on the flow in a differentiallyheated cavity at intermediate and transitional Rayliegh numbers. The results are in a very good agreement with other available numerical solutions.
