Pulsatile flow of plastic fluids through porous elastic pipes

A numerical resolution concerning pulsatile flows of plastic fluids through porous elastic ducts is presented. The objective is to investigate the effects ofporosity, and elasticity of pipe wall material for a generalized Bingham fluid. An implicit difference method is used to resolve the equations, we determine the axial and radial velocities profiles. This study, considered as a step in modelling of flow in blood vessels, may also contribute to other important fields such as water desalination or gel filtration.
