Peristaltic transport of Johnson-Segalman fluid under effect of a magnetic field

Abstract

The peristaltic transport of Johnson-Segalman fluid by means of an infinite train of sinusoidal waves traveling along the walls of a two-dimensional flexible channel is investigated. The fluid is electrically conducted by a transverse magnetic field. A perturbation solution is obtained for the case in which amplitude ratio is small. Numerical results are reported for various values of the physical parameters of interest. Copyright © 2005 M. Elshahed and M. H. Haroun.
