Oscillatory Flow of Dusty Fluid Through a Narrowed Channel in the Presence of Magnetic Field

Investigation of pulsatile flow of a dusty fluid in the presence of magnetic filled through a two-dimensional restricted channel is done. Stream function, fluid velocity, the velocity of dust particles and pressure distribution have been studied and a solution is obtained using the perturbation method under long-wavelength approximation. It has been observed that the streamline changes as magnetic parameter changes. Also when the parameter of magnetic effects increases the shear stress of the fluid increases but pressure decreases.
