Abstract

The effects of variable viscosity and thermal conductivity on the MHD flow of micropolar fluid on a continuous moving surface in the presence of a transverse magnetic field are studied considering the viscosity and thermal conductivity as the inverse linear functions of temperature where the microinertia density is assumed to be variable and not constant, as many other earlier published papers. Also, the viscous dissipation effect is taken into account. The partial differential equations governing the flow and 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 method. The effects of various parameters viz. viscosity parameter, thermal conductivity parameter, magnetic parameter, coupling constant parameter, Eckert number and Prandtl number on velocity, micro-rotation, temperature field and micro-inertia density are studied and results are presented graphically. The co-efficient of skin-friction and Nusselt number are also computed and presented in tabular form.
