VISCOUS DISSIPATION AND OHMIC HEATING EFFECTS ON MAGNETOHYDRODYNAMIC MIXED CONVECTION ALONG A VERTICAL MOVING SURFACE EMBEDDED IN A FLUID-SATURATED POROUS MEDIUM
ABSTRACT
The effects of both first- and second-order resistance, due to the solid matrix of non-Darcy porous media, viscous dissipation, Ohmic heating, and temperature-dependent viscosity on laminar mixed convection boundary layer flow and heat transfer on a continuously moving vertical surface, have been studied. The fluid viscosity is assumed to vary as an inverse linear function of temperature under the action of a transverse magnetic field. Local similarity solutions are obtained for the boundary layer equations governing the flow along a moving vertical isothermal surface with uniform velocity. The effects of various parameters, such as the first- and second-order solid matrix resistance, magnetic field, Eckert number, buoyancy force, and viscosity/temperature parameter, on the velocity and temperature profiles as well as the skin friction coefficient and wall heat transfer are presented graphically and in tabular form.
