Soret and Dufour effect on double diffusion mixed convection from a vertical surface in a porous medium saturated with a non-Newtonian fluid

Convection from an inverted cone in a porous medium with cross-diffusion effects

“…Table 3 illustrates the effects of buoyancy parameter N 1 on the shear stress f ′′ (0) between the fluid flow and the cone surface, the Nusselt number and the Sherwood number. Increasing fluid buoyancy enhances the wall shear stress and the local heat and mass transfer rates; see Mahdy [31]. Table 4 Effect of λ on the skin-friction, heat and mass transfer coefficients when N 1 = 0.5, Λ = 0.5, D f = 0.1, S r = 0.…”

Double diffusive natural convection in power-law fluid saturated porous medium with Soret and Dufour Effects

“…The effect of Soret and Dufour parameters on free convection heat and mass transfers from a vertical surface in a doubly stratified Darcian porous medium has been reported by Lakshmi Narayana and Murthy (2007). Mahdy (2010) presented a non-similar boundary layer analysis to study the flow, heat and mass transfer characteristics of non-Darcian mixed convection of a nonNewtonian power law fluid from a vertical isothermal plate embedded in a homogeneous porous medium with the effect of Soret and Dufour and in the presence of either surface injection or suction. It was observed by him that increases in the Soret number tended to increase the local heat transfer rate while decreasing the mass transfer rate.…”

“…They observed that the strong influence of the Darcy number on heat transfer is more complex than in thermal convection, and then the behavior of the thermosolutal flow in porous media is different from the behavior already assessed for fluids. Mamou et al (1996) have carried out analytical and numerical study of double diffusive convection in a vertical enclosure. In his analytical study, he applied a scale analysis to the two extreme cases of heat-transfer and mass-transfer-driven flows and then an analytical solution, based on the parallel flow approximation, is reported for tall enclosures.…”

Dufour and Soret Effects on MHD Forced Convective Heat and Mass Transfer Flow of Non-Newtonian Power Law Fluid with Thermal Radiation and Viscous Dissipation

“…M. S. Alam et al [17] investigated Dufour and Soret effects on unsteady MHD free convection and mass transfer flow past a vertical porous plate in a porous medium. Mahdy [18] studied Soret and Dufour effect on double diffusion mixed convection from a vertical surface in a porous medium saturated with a non-Newtonian fluid. Chen et al [19] analyzed Soret and Dufour effects on free convection flow of non-Newtonian fluids along a vertical plate embedded in a porous medium with thermal radiation.…”
