The Peristaltic Flow of Williamson Fluid through a Flexible Channel

The purpose of this study is to investigate the effect an elastic wall on peristaltic flow Williamson fluid between two concentric cylinders, where inner tube cylindrical with inelastic and outer a regular sine wave. For problem, coordinates are used short wavelength relative channel width for its length, as well governing equations in Navier-Stokes equations. results evaluated using Mathematica software program. program by entering various data parameters, shows graphs, then these parameters became clear mentioned conclusion. through conduit subject investigation. number significant elements, such velocity distribution, stress wave frame streamlines, graphic findings supplied at end article.
