Magnetohydrodynamic boundary layer with pressure gradient and suction

The combined effects of suction and magnetodynamic pressure gradient on a viscous steady incompressible electrically conducting fluid of constant properties near the leading edge of a porous semi-infinite plate with an applied magnetic field have been studied. The two-point boundary value problem governed by coupled nonlinear ordinary differential equations has been solved numerically using a method of solution that is based on least-squares convergence criterion which leads to the unique solution of the problem. The results show that the skin friction and the tangential component of the magnetic field increase with the suction velocity and the magnetodynamic pressure gradient. (author)
