Oscillatory Magnetohydrodynamic Flow past a Flat Plate with Hall Effects

Abstract

Hall effects on the hydromagnetic flow past a flat plate in the presence of a uniform transverse magnetic field has been analysed when the free stream oscillates in magnitude only. Solution is obtained for the velocity field for small amplitude oscillations. For small frequency oscillations of the free stream the increase in Hall parameter increases the phase difference of the oscillations of the shearing stress. The resonance frequency of the boundary layer decreases with the increase in Hall parameter.
