Hydromagnetic Flow Between Two Parallel Porous Walls in a Rotating System

Abstract

The effect of uniform transverse magnetic field is investigated on the flow formed, when a straight channel formed by two parallel porous walls through which liquid is flowing under a constant pressure gradient, is rotated about an axis perpendicular to the walls. The flow depends on the Taylor's number alpha pressure gradient p, the suction Reynolds number beta and the Hartmann number M. When alpha limit infinity such that p is finite, thin boundary layers are formed in the vicinity of the porous walls and the effect of the magnetic field is to reduce the thickness of the boundary layers. A method for setting up an experiment to test the theoretical conclusions of the paper has been suggested.
