This work concerns the peristaltic flow of a Williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. The governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. The analytical results are computed with the help of regular perturbation and the numerical re...

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 Mathematic...

Peristaltic transport of a Williamson fluid in an asymmetric channel through porous medium is studied under long wavelength and low Reynolds number assumptions. The nonlinear governing equations of the peristaltic flow are solved using perturbation method. The solution for the stream function is obtained by neglecting inertia and curvature effects. The velocity distribution, the volume flow rat...
