Résumé

Several corrections are introduced to the Elliptic Blending Differential Flux Model proposed by Shin et al. (2008). The suggested formulation can deal with the different flow regimes; forced, mixed and natural convection. It gives very encouraging results for two channel flows in forced and mixed convection and for a cavity flow in the natural convection regime.
