About the Carotid Bifurcation CFD Analysis Project
This CFD simulation investigates blood flow through a carotid bifurcation, where the common carotid artery divides into the internal carotid artery (ICA) and external carotid artery (ECA). The steady-state simulation captures the velocity field, pressure distribution, and wall shear stress patterns within the bifurcating arterial geometry. Blood is modeled as an incompressible non-Newtonian fluid using the Carreau–Yasuda viscosity model, allowing the viscosity to vary with local shear rate. The vessel walls are treated as rigid no-slip boundaries, while a prescribed inlet velocity is applied at the common carotid artery. Flow exits through the ICA and ECA outlets according to the specified outlet conditions. The results highlight important hemodynamic features such as flow acceleration near the bifurcation, pressure drop across the branches, and localized wall shear stress regions along the vessel wall. This type of simulation is useful for studying carotid artery flow behavior and identifying regions where complex flow patterns may occur. CAD model used in this CFD analysis is by Abdu Yearwood (https://grabcad.com/abdu.yearwood-1)
