Abstract

Pulsatile flow of a Saffman’s dusty fluid through a two dimensional constricted conduit in the existence of magnetic field is investigated. Perturbation solutions have been obtained under long wave length approximation and closed form expressions have been derived for stream function, velocities of solid and fluid particles, pressure distribution and shear stress. It is found that the streamlines get altered as magnetic parameter rises. The shear stress of the fluid acting on the wall increases with magnetic parameter but the pressure decreases.
