Heat and Mass Transfer past a Continuously Moving Porous Boundary in the Presence of a Magnetic Field

The effect of magnetic field on the flow and heat and mass transfer processes when the fluid flows past a continuously moving porous plate has been analyzed. The governing boundary layer equations have been reduced to a set of nonlinear ordinary differential equations using similarity transformations. The governing equations are solved using an implicit finite-difference scheme of Crank-Nicolson type. The effects of magnetic and suction (or injection) parameters on the velocity, temperature and concentration profiles as well as on the heat transfer coefficient have been studied numerically and are shown in figures. Numerical computations have been carried out for different values of fw and and for fixed values of Sc.
