Abstract

The slip effect on hydromagnetic rotating flow of viscous fluid through a porous space is investigated. The fluid is electrically conducting with the consideration of Hall current. The entire system rotates about the axis normal to a porous plate of uniform suction or injection with uniform angular velocity. The closed form solution is obtained using Laplace transform technique. The analytical expression for skin friction is evaluated. The graphical results are displayed to see the effects of various embedded flow parameters such as magnetic parameter , permeability parameter , Hall parameter , rotation parameter , suction or injection parameter , slip parameter  and dimensionless time  It is found that the magnetic field and slip parameter decrease the velocity magnitude whereas permeability and Hall parameters increase it. The slip and magnetic field play an important role in retarding the growth of both the primary and secondary flows, whereas Hall parameter enhances the flow.
