An analytical study of unsteady dusty fluid flow between two oscillating plates has been considered. The flow is due to influence of nontorsional oscillations of plates and pulsatile pressure gradient. Flow analysis is carried out using differential geometry techniques and exact solutions of the problem are obtained using Laplace Transform technique. Further graphs drawn for different values of Reynolds number and on basis of these the conclusions are given. Finally, the expressions for skin-friction are obtained at the boundaries.
