• EFFECT OF POROUS LINING ON THE PERISTALTIC TRANSPORT OF A CASSON FLUID IN AN INCLINED CHANNEL

Abstract

Peristaltic transport of a Casson fluid in an inclined channel is investigated. The effect of porous lining has been studied under long wavelength and low Reynolds number assumptions. The equations of motion are solved analytically and the expressions for velocity, stream function and flow rate are obtained. The pumping and trapping phenomena are analyzed. The effect of porous lining, yield stress, amplitude ratio, permeability parameter and angle of inclination on the pumping characteristics are discussed graphically. Trapping limits are obtained for the stream function of the fluid flow. The results are interesting and warrant further study on the peristaltic transport of yield stress fluids.
