摘要

In this study, we consider the fluid flow and heat transfer analysis of electrically conducting MHD Newtonian fluid through an annular sector duct, which is filled with a Darcy-Brinkman porous medium, under the action of an axially applied constant pressure gradient and uniform transverse magnetic field. The finite volume method (FVM) is used to discretize the governing momentum and energy equations. The behavior of velocity and temperature contours, and similarly velocity and temperature profiles against pertinent parameters like the Hartman number Ha and dimensionless permeability factor (K) over tilde are displayed graphically for different channel configurations and explained in a physical manner. Physical quantities of interest such as bulk mean velocity (w) over cap (m) and friction factor fRe are used to explain the fluid flow behavior, whereas the bulk mean temperature tau(b) and average Nusselt number Nu are used to explain the heat transfer analysis. Their values are also computed numerically and compared with the literature in the limiting case.
