Abstract

Peristaltic motion of a non-Newtonian, incompressible power law fluid with suspension of small particles in a twodimensional channel is analyzed. A perturbation method has been employed to obtain the solution of the problem under the long wavelength approximation. The formation and growth of trapping zone are explained for variations in amplitude ratio and volume flow rate. The phenomenon of reflux has been studied. The behaviour of the axial velocity of fluid and solid particles has been discussed. The speed of the suspended particles is observed to be less than that of the fluid particles.
