MHD ASYMMETRIC FLOW BETWEEN TWO POROUS DISKS

A numerical study is presented for steady incompressible viscous MHD asymmetric flow of an electrically conducting fluid between two infinite parallel stationary coaxial porous disks of different permeability in the presence of a transverse magnetic field. The main flow is superimposed by a constant injection at the surfaces of the disks. The governing non linear partial differential equations together with the boundary conditions are reduced to non linear ordinary one using Von Karman's similarity transformation. An algorithm based on finite difference discretization is used to solve the obtained boundary value problem. The results are presented in tabular and graphical forms to discuss important features of the flow. Comparisons with the previously published literature work are found to be in a good agreement in the absence of magnetic field. The present investigations show that magnetic field enhances shear stresses. The position of viscous layer changes with the permeable parameter.
