About the Carotid bifurcation cfd simulation Project
This CFD simulation investigates blood flow through a second carotid bifurcation geometry (check Refetch below for first geometry), where the common carotid artery divides into the internal carotid artery (ICA) and external carotid artery (ECA). This geometry provides an additional bifurcation configuration for comparing how vessel shape, branch angle, and outlet diameter influence the local hemodynamics. Blood is modeled as an incompressible non-Newtonian fluid using the Carreau–Yasuda viscosity model, allowing the blood viscosity to vary with local shear rate. The arterial wall is treated as a rigid no-slip boundary. A prescribed inlet velocity is applied at the common carotid artery, while flow exits through the ICA and ECA outlets according to the specified outlet boundary conditions. The steady-state simulation captures key flow features such as velocity acceleration near the bifurcation, pressure drop from the common carotid inlet to each outlet, and wall shear stress distribution along the vessel wall. Localized high-WSS regions may appear near the bifurcation apex, curved branch regions, or narrowed vessel sections where the flow experiences stronger near-wall velocity gradients. This case is useful for visualizing and analyzing carotid artery hemodynamics in an alternative bifurcation geometry, especially the influence of branch morphology on pressure, velocity, and wall shear stress patterns. CAD model used in this CFD analysis is by Aaron (https://grabcad.com/aaron-435)
