Peristaltic flow of viscoelastic fluid with fractional Maxwell model through a channel

Abstract

The paper presents the transportation of viscoelastic fluid with fractional Maxwell model by peristalsis through a channel under long wavelength and low Reynolds number approximations. The propagation of wall of channel is taken as sinusoidal wave propagation (contraction and relaxation). Homotopy perturbation method (HPM) and Adomian decomposition method (ADM) are used to obtain the analytical approximate solutions of the problem. The expressions of axial velocity, volume flow rate and pressure gradient are obtained. The effects of fractional parameters (α), relaxation time (λ1) and amplitude (φ{symbol}) on the pressure difference and friction force across one wavelength are calculated numerically for different particular cases and depicted through graphs. © 2009 Elsevier Inc.
