Mixed convection of magneto hydrodynamic and viscous fluid in a vertical channel

Abstract

Mixed convective flow and heat transfer in a vertical channel with one region filled with conducting fluid and another region with non-conducting fluid is analyzed. The viscous and Ohmic dissipation terms are included in the energy equation. Three types of thermal boundary conditions such as isothermalisothermal, isofluxisothermal and isothermalisoflux for the leftright walls of the channel are prescribed. Analytical solutions are found for the governing equations using the regular perturbation method. A selected set of graphical results illustrating the effects of various parameters involved in the problem are presented and discussed. © 2010 Elsevier Ltd. All rights reserved.
