RT Journal Article ID 3e5002d62057d269 A1 Khan, Masood T1 Exact Solutions for the Accelerated Flows of a Generalized Second-Grade Fluid between Two Sidewalls Perpendicular to the Plate JF Journal of Porous Media JO JPM YR 2009 FD 2009-09-12 VO 12 IS 9 SP 919 OP 926 AB This paper is concerned with the exact solutions for the accelerated flows of a generalized second-grade fluid through a porous medium with a fractional derivative model. The fractional calculus approach is taken into account in the constitutive relationship of a non-Newtonian fluid model. Two characteristic examples, which are flow due to a constantly accelerating plate and flow due to variable accelerating plate between two sidewalls perpendicular to the plate, are considered. Employing the Fourier sine transforms and the theory of the Laplace transform for fractional calculus, the exact solutions are obtained. The solutions for a second-grade fluid appear as the limiting cases of the presented solutions by setting β = 1. Furthermore, in the absence of sidewalls, all solutions that have been constructed reduce to the known solutions of second-grade and Newtonian fluids corresponding to the motion over an infinite flat plate.
