Magnetohydrodynamic effects upon momentum transfer on a continuously moving flat plane

AbstractThe present paper is concerned with the interesting situation of the existence of a transversal momentum boundary layer in the case of flow induced by a continuously moving flat plate under an applied magnetic field besides the axial boundary layer. An approximate analytical technique by using a power-series expansion method for the governing equation has been developed to investigate the velocity field inside the laminar boundary layer. The analysis shows that the transversal boundary layer is thicker than the axial boundary layer. However, the increase in the magnetic parameter B decreases the boundary layer thickness. The expression for the skin-friction coefficient is obtained for different values of B
