Hall effects on unsteady MHD rotating flow past a periodically accelerated porous plate with slippage

Abstract This paper investigates the effects of slip condition on an unsteady magnetohydrodynamic (MHD) flow of a viscous incompressible electrically conducting fluid past a periodically accelerated horizontal porous plate under the influence of transverse magnetic field and Hall current. A uniform magnetic field is applied transverse to the direction of the flow. The flow is generated due to the accelerated motion of the porous plate. A unified closed form analytical solution of governing equations has been obtained by employing the Laplace transform technique. The influences of the pertinent parameters on the velocity field and shear stress are displayed through graphs. The numerical results reveal that an increase in Hall parameter leads to an increase in momentum boundary layer thickness.
