Résumé

This study concerns the two-dimensional numerical simulation of the double diffusive convection in cylindrical vertical annular cavity. The vertical walls are maintained at different uniform temperatures and concentration. The governing equations are solved numerically using the finite volume method. The coupling between the continuity and momentum equations is effected using the SIMPLER algorithm. Numerical analysis has been carried out for a wide range of the buoyancy ratio (N=0,8 and 1,3). The influence of the buoyancy ratio (N) parameters on the streamlines, isotherms, isoconcentration, average Nusselt number and Sherwood numbers has been numerically investigated in detail.
