This paper develops a mathematical model with an aim to compute the analytic solution for the flow of a fourth grade fluid between two fixed porous walls. The flow is induced under the application of a constant pressure gradient. The arising nonlinear problem is treated analytically yielding a serie

We solve the governing equations for the flow of a third grade fluid in a porous half space. We find a simple expression which describes the solution accurately over the whole domain Β½0; 1Γ. The rate of exponential decay of the flow is independent of the parameters which characterize the nonlinear p
The steady flow of a second grade fluid in a porous channel is considered. The constitutive equations are those used for a second grade fluid. The fluid is electrically conducting in the presence of a uniform magnetic field applied in the transverse direction to the flow. It is shown that an analyti
A new analytic approximate technique for addressing nonlinear problems, namely the Optimal Homotopy Asymptotic Method (OHAM), is proposed and used in an application to the steady flow of a fourth-grade fluid. This approach does not depend upon any small/large parameters. This method provides us with
