HPM Solution of an unsteady non-Newtonian Fluid between Stationary and Oscillating Plates

Recent work deals with the study the flow of a generalized third order fluid among two parallel plates. The flow of fluid is due to the motion of oscillated plate and pressure gradient. Three special categories of flows namely, Couette, Poiseuille and Plug flows, are considered. The non-linear Partial differential equations (PDE) are solved analytically by using Homotopy Perturbation Method (HPM). Finally, effect of the physical parameters on the fluid motion have been plotted and discussed.
