MHD Flow through a Porous Walled Circular Cylinder Filled with Porous Medium in the Influence of Cosinusoidal Suction on the Wall

Abstract

Two dimensional axisymmetric viscous incompressible electrically conducting fluid flows through a circular cylinder filled with porous medium in the presence of a static transverse magnetic field and a cosinusoidal suction in radial direction is studied. A domain Decomposition Method (ADM) is used to solve the non-linear coupled differential equation to obtain the velocity profiles in radial and axial direction. The effects of involved physical parameters are computed and discussed graphically. The skin-friction coefficient is also computed and effect of Reynolds number, Hartmann number and Darcy number are analyzed.
