CHEMICAL REACTION AND RADIATION EFFECTS ON NATURAL CONVECTION IN POROUS MEDIUM SATURATED WITH POWER-LAWFLUID

Radiation-Convection Flow in Porous Medium with Chemical Reaction

We study magnetohydrodynamic radiation-convection flow through a porous medium with mass transfer in the presence of a homogeneous first order chemical reaction and surface temperature oscillation. The governing equations are solved analytically using perturbation technique. Detailed computations of the influence of Hartmann number, frequency of the oscillation, radiation parameter, Prandtl num...

Double Diffusive Natural Convection in Power-Law Fluid Saturated Porous Medium with Soret and Dufour Effects

The effects of double diffusive natural convection heat and mass transfer along a vertical plate embedded in a power-law fluid saturated Darcy porous medium in the presence of Soret and Dufour effects are studied. The governing partial differential equations are transformed into ordinary differential equations using similarity transformations and then solved numerically. A parametric study of t...

Effects of Radiation and Chemical Reaction on Heat and Mass Transfer by Natural Convection in a Micropolar Fluid-saturated Porous Medium with Streamwise Temperature and Species Concentration Variations

In this paper, the problem of coupled heat and mass transfer by a natural-convection boundary-layer fl ow of a micropolar fl uid past a vertical fl at plate in a saturated porous medium with streamwise sinusoidal variations of both the surface temperature and species concentration in the presence of thermal radiation and chemical reaction eff ects is investigated. A suitable set of dimensionles...

Chemical reaction and radiation effects on MHD free convection flow through a porous medium bounded by a vertical surface with constant heat and mass flux

In the present paper, an analysis was carried out to investigate effects of radiation on a free convection flow bounded by a vertical surface embedded in a porous medium with constant suction velocity. It was under the influence of uniform magnetic field in the presence of a homogenous chemical reaction and viscous dissipation with constant heat and mass flux. The non-dimensional governing equa...
