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