• HYDROMAGNETIC OSCILLATORY FLOW OF DUSTY FLUID IN A ROTATING POROUS CHANNEL

Abstract

An analysis of the unsteady flow of a dusty viscous, incompressible, electrically conducting fluid in a horizontal porous channel rotating with an angular velocity under the influence of periodic pressure gradient is studied. The lower porous plate is subjected to a uniform injection and the upper porous plate to a uniform suction. A magnetic field of uniform strength is applied perpendicular to the plates. The magnetic Reynolds number is assumed to be small enough so that the induced magnetic field is negligible. The whole system in unison rotates about the axis normal to the plates. Analytical solutions for the velocities of the fluid and the dust particles are obtained. The effect of the various parameters on the governing equations of the fluid velocity and the dust particles has been numerically evaluated, shown graphically and discussed.
