... for a correct handling of the discontinuity of the macroscopic properties are analyzed. A particular class of problems dealing with thermal and double diffusive natural convection mechanisms in partially porous enclosures is presented, and it is shown that this configuration exhibits specific features in terms...

... of the computations, which respond to the geometric parameters, fluid nature, thermofluid dynamic parameters and porous matrix characteristics. The collection of numerical results elucidates that the double diffusion zone varies and, besides it is strongly dependent on the coupling between the Prandtl and Lewis...
