Abstract
In this paper the influence of inclined magnetic field on the peristaltic flow of a Williamson fluid in an inclined symmetric or asymmetric channel has been investigated initially in the wave frame of reference. The highly nonlinear equations are simplified under lubrication approach. The analytical and numerical solutions of the proposed problem have been computed and analyzed. The graphical results are displayed to see the effects of various physical parameters of interest. (C) 2010 Elsevier Ltd. All rights reserved.
