Examination of the blood flow in the carotid artery is an important issue in hemodynamic studies. Conditions such as atherosclerosis, stenosis and aneurysm in blood vessels cause cardiovascular diseases. In such cases, it will be useful to examine blood flow using Computational Fluid Dynamics for determining blood flow velocities, shear stresses on the vessel walls and having a preliminary idea about medical interventions to be performed accordingly. The studies in this process can be based on real carotid artery geometries, or it can be obtained from patient data and working on bifurcated artery geometries close to real geometry to improve problematic vascular structures. The vessel geometry can be simulated by taking the real geometries obtained from the CT images and reconstruction them according to the suitable mesh types for CFD analysis, and the blood flow velocity and shear stresses in the vessel wall can be calculated for critical vessel regions. High computer capacity may be needed to get the real vessel geometry and make this geometry suitable for analysis. For this reason, in this study, the behavior of the flow was examined by focusing on the critical points such as where the bifurcation begins, the bifurcation angle and the diameters of branches on the suitable Y-shape geometry . The results were examined by making angular and diametral changes in the Y-shape.
OpenFOAM which is an open source software programme was used in the analyzes made in terms of Computational Fluid Dynamics. The vessel geometry can be created by changing critical parameters in OpenFOAM.
