A Stabilized Finite Element Formulation of Non-Newtonian Fluid Model of Blood Flow in A Bifurcated Channel with Overlapping Stenosis

A stabilized form of finite element formulation known as the Galerkin least-squares (GLS) method is implemented here for solving two-dimensional incompressible non-Newtonian fluid model blood flow in a diseased artery. The modelling this type based on conservation mass and momentum equations, coupled with generalised Newtonian liquid (GNL) constitutive equation characterized by power law (GPL) model. present study are assumed steady, laminar fully developed. algorithms considered herein first solved straight artery bell shaped stenosis validation purposes. As efficiency validity proposed obtained through comparison findings from existing literature COMSOL Multiphysics 5.2 software. Then, being to bifurcated overlapping located at parent's arterial lumen. numerical results illustrate arising distinct sizes vortex shedding downstream stenotic region each index.
