Abstract

This investigation deals with the peristaltic motion of a Carreau fluid in a planar channel by employing long wavelength approximation. Five wave forms are chosen. Explicit solutions of longitudinal velocity and pressure gradient are derived. The pumping and trapping phenomena are properly examined. Comparison is made for the flow characteristics of the various selected wave forms. Β© 2009 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq 2010

## Abstract An analysis describing the peristalsis of non‐Newtonian fluids in a symmetric channel is carried out. Two explicit forms of Phan‐Thien‐Tanner model are used in the flow description. Mathematical analysis is presented at small Reynolds number and large wavelength assumptions. The influen
