Exact solutions of a third grade fluid flow on a porous plate

摘要

In this paper, the exact solutions for an unsteady flow of an incompressible fluid of third grade occupying space over an infinite porous plate are obtained for a given velocity component. Translational type symmetries are employed to reduce the non-linear equations governing the flow under discussion to two ordinary differential equations (with and without dispersion terms). Graphs representing the solutions are discussed, and appropriate conclusions drawn.
