EFFECTS OF VARIABLE VISCOSITY AND THERMAL CONDUCTIVITY ON MHD CONVECTIVE HEAT TRANSFER OF IMMISCIBLE FLUIDS IN A VERTICAL CHANNEL

The effects of variable viscosity and thermal conductivity on the MHD flow of two immiscible fluids in a vertical channel are presented. The differential equations governing the flow, heat transfer of the problem are transformed into dimensionless form of ordinary differential equations by using similarity substitutions. The governing boundary value problems so obtained are then solved numerically using Runge-Kutta 6th order method. The effects of pertaining parameters on velocity and temperature field are studied and results are presented graphically. The co-efficient of skin-friction and Nusselt number are also computed and presented in tabular form
