Numerical Approach of Non-Newtonian Fluid Flows in a Bifurcation Channel

The investigation of non-Newtonian fluid flow behaviors are discussed in a bifurcated channel using Lattice-Boltzmann Method (LBM) in our study. This method is established on the D2Q9 model, and the single-relaxation-time (SRT) method called the Lattice-BGK (Bhatnagar-Gross-Krook) model. The flow patterns are similar to blood flows in branched arteries for bifurcation flows. Firstly, the code validation is performed for the Newtonian fluid flows by comparing the available published results. The numerical outcomes are calculated for the different Reynolds number Re, power-law index n and the outlet flow rate ratioβ. The outcome of this relevant parameter on the streamlines, vortices, velocity distribution, recirculation zones as well as shear stress will be studied to analyze the hemodynamic of blood flows near arterial bifurcations
