Abstract
In the present investigation we have studied the peristaltic flow of a Jeffrey fluid in a rectangular duct. The flow is investigated in a wave frame of reference moving with the velocity c away from the fixed frame. The peristaltic waves propagating on the horizontal sidewalls of a rectangular duct is studied under lubrication approach. The exact solutions of velocity and pressure gradient have been found under lubrication approach. The pumping characteristics, axial pressure gradient, velocity field and trapping phenomena have been discussed to highlight the physical features of emerging parameters of the Jeffrey fluid. The comparison is also made with the existing literature. (C) 2010 Elsevier Ltd. All rights reserved.
