EFFECT OF COMPLETE SLIP ON PERISTALTIC TRANSPORT OF JEFFREY FLUID FLOW IN A TAPERED CHANNEL WITH SUCTION AND INJECTION

The present paper investigates the effect of completer slip on Peristaltic transport of a Jeffrey fluid in a tapered channel with suction and injection. The mathematical modelling has been carried out under long wavelength and low Reynolds number approximation. The analytical solution for velocity field, pressure gradient, frictional force and stream function in the wave frame of reference are obtained. The pressure rise and frictional force over one wave length are obtained. The effect of different physical parameters on pumping characteristics and frictional forces are discussed graphically. It is observed that pressure rise decreases with increasing permeability parameter and increases with increasing amplitude. It is also observed that for various values of suction parameter k , the pumping curves coincide at a point in the first quadrant due to the suction or injection in the channel. The frictional forces illustrate the opposite behavior compared to pressure rise. The trapping phenomenon for different parameters is presented graphically
