Impact of the Permeable Wall Lining on the Peristaltic Flow of Williamson Fluid in an Inclined Channel

The peristaltic flow of Williamson fluid in an inclined channel is studied. The walls of the canals are lined with a porous material. The flow is generated due to the propagation of sine wave trains on the walls. To determine the model, assumptions are made about the long wavelength and low Reynolds number. The solutions for the pressure gradient and also the friction forces have been obtained for a diminutive Weissenberg number, by means of a disturbing expansion around Weissenberg number. We also confer the graphical results of pressure increase, frictional force, and time-averaged volumetric flow rate for an assortment of amplitude ratio values, permeability parameter, lining, Weissenberg number, Reynolds number and angle of inclination.
