Perturbation Unsteady Flows of 1-D Fluid

This paper studies about the grade-III fluid having unidirectional and unsteady flow, possessing acceleration. Non-linear partial differential equation, having the slip condition, is solved using perturbation method & similarity transform. The Newtonian fluid is determined by Navier having 3-unsteady, non-linear, partial differential equations. The solution of this fluid is solved using the similarity and by applying perturbation method at zeroth and first order. The zeroth velocity ( ) solution leads to the solution of grade-II fluid and first velocity ( ) contribute in finding the solution of the grade-III fluid.
