Abstract
The Peristaltic transport of a Williamson fluid in a porous channel with suction and injection is
investigated. A perturbation technique in terms of small Wessienberg number has been carried out to
determine the expressions for the velocity, the stream function, the pressure rise and friction force
under long wavelength and low Reynolds number assumptions The effects of different parameters on
the pumping characteristic and frictional force are discussed graphically.
