The Effect of a Pulsatile Flow on the Peristaltic Output: Case of a Newtonian Fluid
H. Rachid, M. T. Ouazzani · 2008
In this paper we studied the effect of pulsatile flow on the peristaltic transport. The flow is considered unsteady even in the wave frame analysis where we suppose that the flow rate imposed, in this frame, is a function versus time. This transport is studied under low Reynolds number and long wavelength approximations. The governing equations are developed up to the second-order in the Womersley number. We have analyzed the influence of different problem parameters on the re-lation pressure rise-flow rate, on the relation friction force-flow rate and on the peristaltic output.
