Radiation Effects on MHD Natural Convection Heat Transfer Flow from Spirally Enhanced Wavy Channel through a Porous Medium

Abstract

The objective of this paper is to study the radiation effects on magnetohydrodynamic natural convection heat transfer flow from spirally enhanced wavy channel through a porous medium and a smooth flat wall. A uniform magnetic field is assumed to be applied normal to the insulating walls of the channel. The governing equations of the flow field are solved nu using regular perturbation technique subject to the appropriate boundary conditions. The solution of the mean part and total solution of the problem have been evaluated analytically for various parameters pertaining to the problem and are presented graphically.
