Effect of magnetic field on unsteady free convection flow over a vertical wavy surface

Nepal C. Roy, S. Sultana

Abstract


Unsteady free convection flow over a vertical wavy surface in the presence of magnetic field is presented. The governing equations are
reduced to a system of dimensionless equations by using appropriate transforms. Resulting equations are then solved numerically
employing implicit finite difference method. Effects of the amplitude-wavelength ratio and the magnetic field parameter are discussed in
terms of the local skin-friction coefficient, the local Nusselt number and the local Sherwood number.
