Abstract
Peristaltic transport of a Casson fluid in a channel with perme-able walls is investigated. Exact analytical solution of the flow quantities are developed under long wavelength and low Reynolds number assumptions. The effects of Darcy number and yield stress on the pumping characteristics are obtained and discussed. It is observed that for a given δP, the flux Q̄ decreases with increasing Darcy number. Further, it is noticed that for a given δP, the flux Q̄ decreases with increasing yield stress τ . This may be due to the yield stress behaviour of the Casson fluid. The results of the trapping phenomenon are analyzed. Four different wave forms are considered. The comparison of the different wave forms is discussed. © 2014 Academic Publications, Ltd.
