This paper examines the variable thermal conductivity influence on MHD flow past a thermally stratified stretching cylinder with heat source or sink. The governing partial differential equations of the flow field are converted to a system of non-linear coupled similarity ordinary differential equations. Employing Shooting technique followed by Runge-Kutta method, the system is solved numerically. The effects of the various physical parameters countered in the flow field on the velocity, temperature as well as the skin friction coefficient and the rate of heat transfer near the wall are computed and illustrated graphically. © 2017, Global Digital Central.

Frontiers in Heat and Mass Transfer

An analysis of the thermal radiation and viscous dissipation effects on an unsteady MHD mixed convection flow of a viscous incompressible fluid past a vertical porous plate, in the presence of variable wall heat flux and heat generation/absorption is presented. The free stream velocity follows an exponentially increasing or decreasing small perturbation law. The governing equations of the flow field are transformed into a system of non-linear ordinary differential equations by perturbation technique and then solved numerically by using the shooting method. The effects of the various parameters on the translation velocity, microrotation and temperature as well as the skin friction coefficient and couple stress coefficient at the wall are prepared with various values of the fluid properties.
