RADIATION EFFECT ON NATURAL CONVECTION OVER AN INCLINED WAVY SURFACE EMBEDDED IN A NON-DARCY POROUS MEDIUM SATURATED WITH A NANOFLUID
要約
The effect of radiation on free convection over an inclined wavy surface embedded in a non-Darcy porous medium saturated with nanofluid is studied. A coordinate transformation is used to transform the complex wavy surface to a smooth surface. The governing equations are transformed into a set of ordinary differential equations using similarity transformations and then solved by successive linearization method. The Rosseland approximation is used to describe the radiative heat flux in the energy equation. The present results are compared with previously published work and are found to be in very good agreement. The effects of Grashof number, radiation parameter, Brownian motion parameter, thermophoresis parameter, amplitude of the wavy surface, angle of inclination of the wavy surface on the non-dimensional velocity, temperature, nanoparticle volume fraction, heat, and nanoparticle mass transfer rates are studied and presented graphically.
