Abstract

In this paper, non-Newtonian fluid flow behaviors are analyzed in a two-dimensional T junction channel using Lattice-Boltzmann Method (LBM). The LBM has been built up on the D2Q9 model, and the single-relaxation-time (SRT) method called the Lattice-BGK (Bhatnagar-Gross-Krook) model. The flow patterns are analogous to blood flows in branched arteries for T junction flows. Firstly, the code validation has been occurred for the Newto-nian fluid flows by comparing the accessible published results. The numerical outcomes are calculated for the different Reynolds number Re, power-law index η and the outlet flow rate ratio β. The effects of this pertinent parameter on the streamlines, vortices, velocity distribution, recirculation zones as well as shear stress will be discussed to analyze the hemodynamic of blood flows near arterial bifurcations.
