Abstract
The steady incompressible magneto-hydrodynamic (MHD) flow past a circular cylinder with an aligned magnetic field is studied for the Reynolds number (Re) up to 40, using the Hartmann number, M as the perturbation parameter. The multigrid method with defect correction technique is used to achieve the second order accurate solution of complete nonlinear Navier-Stokes equations. The magnetic Reynolds number is assumed to be small. It is observed that as M is increased the volume of the separation bubble decreases and drag coefficient increases. The graphs of streamlines, vorticity lines, surface pressure, surface vorticity and drag coefficient are presented and the effect of the magnetic field is discussed.
