Convective heat and solute transfer in partially porous cavities

Double Diffusive Natural Convection in a Partially Layered Cavity with inner Solid Conductive Body

“…As shown in Fig. 3, the present numerical solution is in good agreement with Gobin et al [8]. In accordance to these two validations, the present code can be used to obtain the results with high confidence level.…”

“…The present numerical solution was further validated by comparing the present numerical solution results for Ra =10 6 , N = 10, Pr =10, Wp = 0.1 and aspect ratio (ratio between height to width of cavity) is 2 and different other parameters with the numerical results of Gobin et al [8], with same thermal and concentration boundary conditions. The tests are presented as the variation of average Nusselt number with different Darcy and Lewis numbers.…”

“…Bennacer et al [7] analyzed the double diffusive natural convection in an enclosure fitted with two symmetrical porous layers confining a fluid layer. Gobin et al [8] investigated a natural convection driven by combined thermal and solutal buoyancy forces in a binary fluid. They confirmed that the presence of the porous layer has a strong influence on the modification of the flow structure and the consequent modifications of the heat transfer.…”

Numerical Simulation of Conjugate Free Convection in a Vertical Cylinder Having Porous Layer

“…At the same time convective heat transfer in the layer of higher permeability begins to penetrate into the less permeable layer with an increase in the Rayleigh number. Double diffusive natural convection in a vertical cavity containing a layer of a binary fluid and a porous layer has been studied by Gobin et al [15]. The authors have used the macroscopic conservation equations with both Darcy-Brinkman model in the porous layer and Navier-Stokes model in the binary fluid layer.…”

Darcian Natural Convection in Inclined Square Cavity Partially Filled Between the Central Square Hole Filled with a Fluid and Inside a Square Porous Cavity Filled with Nanofluid

“…Goyeau et al (2003) discussed the problem of using one-or two domain formulations for conservation equations. Meanwhile, Gobin et al (2005) studied a particular subclass of such problems where natural convection takes place in a confined enclosure partially filled with a porous medium. Nessrine et al (2010) numerically analyzed the fluid flow and heat transfer in a pipe partially filled with porous media by using Brinkman-ForchheimerLapwood-extended Darcys model.…”
