Evaluate the hemodynamic factors' effects on stenosed arteries with the Carreau model

One of the main causes death is atherosclerosis so, in this work, two models stenosed arteries have been executed numerically to assess hemodynamic effects caused by flow disruptions. Using Computational Fluid Dynamics (CFD) provide information public, particularly surgeons, and assist them reducing risk stenosis. Star-CCM+ software was used perform CFD techniques such as steady, turbulent, non-Newtonian (Carreau) applied at different rate conditions. blood velocity, vorticity, strain rate, wall shear stress for identifying plaque-affected section arteries, results showed that areas there a high velocity due smaller lumen diameter, recirculation region also identified immediately after part, resulting increased plaque development.
