Combined effect of viscous dissipation and Joule heating on MHD forced convection over a non-isothermal horizontal cylinder embedded in a fluid saturated porous medium

The effects of both first- and second-order resistance, due to the solid matrix of non-Darcy porous medium, Joule heating and viscous dissipation on forced convection flow from a horizontal circular cylinder under the action of a transverse magnetic field, has been studied. The case of variable wall temperature conditions is considered. The second-level local non-similarity method is used to convert the non-similar equations into a system of ordinary differential equations. Results for the details of the velocity as well as temperature are shown graphically and the numerical values of the skin friction and the rate of heat transfer are entered in tables.
