Wall shear stress in distensible, porous, elastic and anisotropic tubes, for two-phase pulsatile flows of non-Newtonian fluids

摘要

The main of the present work is to elaborate an expression between wall shear stress and flow rate in porous, anisotropic and elastic tubes, for pulsatile two-phase flows Newtonian fluid-Ostwaldian one. This study is done for the case of small values of Womersley parameter. The present expression generalizes a lot of laws of other authors, allows a direct and separate solution of the local and integral equations governing the flow and brings some information to understand some pathologic processes.
