A THEORETICAL-MODEL OF PULSATILE FLOW OF AN INELASTIC FLUID THROUGH ANISOTROPIC POROUS VISCOELASTIC PIPES

A theoretical study concerning the pulsatile flow of an inelastic flui d through anisotropic porous viscoelastic pipes is presented. The obje ctive is to investigate the effects of porosity, conicity in pause, an isotropy and viscoelasticity of pipe wall material for a generalized C asson fluid. An implicit difference method is used to solve the equati ons, and to determine the axial and radial velocity profiles, the pres sure, the flow rate and the pow rate filtration distributions, the tra nsverse rotation and the wall axial and radial displacement. This stud y, considered as a step in the modelling of flow in blood vessels, may also contribute to other important fields such as water desalination or gel filtration.
