Pulsating flows of non-Newtonian fluids in slowly varying porous tubes of small diameter

A theoretical and experimental study concerning the pulsating flow of a two-component fluid through porous conical ducts in presented. The model corresponds to blood flow through small diameter porous conical vessels. The theoretical approach is based on a finite difference method. The physical hypothesis used was based on findings from simultaneous visualization experiments. The influence of geometrical, hydrodynamical and structural parameters is systematically examined and related to velocity profiles and hydrostatic pressure.
