HALL EFFECTS ON PERISTALTIC FLOW OF A COUPLE STRESS FLUID IN AN INCLINED ASYMMETRIC CHANNEL WITH PERMEABLE WALLS

In this paper we investigated the Hall Effects on peristaltic flow of a couple stress fluids in an inclined asymmetric channel with permeable walls. The study is motivated towards investigating the peristaltic mechanism in the digestive system by considering the particle size effects. Perturbation method has been used to get the solution using long wavelength approximation with low Reynolds number and dynamic boundary conditions. The effect of Hall parameter, couple stress fluid parameter, Hartmann number and permeability parameter on the pumping characteristics, temperature and concentration are discussed graphically
