Human carotid veins are located on both sides of the neck and provide blood to the head, brain and parts of the face. Therefore, the examination of blood flow in the carotid arteries is important in hemodynamic studies. Carotid arteries start from the aortic arch and run from the neck to the head. The common carotid divides into external and internal carotid arteries. Just at the beginning of the internal carotid artery, there is a structure called the carotid sinus (or carotid bulb). Atherosclerotic plaque formations are usually seen in this part. The reason for this is the complex
behavior of the flow formed in this structure. This sinus structure differs in every person. In this study, the two-dimensional carotid artery was designed parametrically in blockMeshdict with OpenFOAM and blood flow analysis was performed on this geometry.
The blood flow in the carotid artery is assumed to be incompressible and laminar. In most studies, the blood flow has been taken as Newtonian flow. In this study, both Newtonian and Non-Newtonian flow types are discussed. "Magnetic Flow Meter", "Ultrasonic Flow Meter", "Laser Doppler Anemometer (LDA)", "Particle Image Velocimetry (PIV)" devices are used for blood flow velocity or flow rate measurements. Flow rate measurements are obtained with Magnetic and Ultrasonic flow meters, velocity values can be measured with LDA and PIV devices. Flow imaging operations can be performed using specialized cameras (such as CCD cameras) and these values are used in related studies. In this study, pulsatile and constant velocity inputs were taken and flow analyzes were obtained.
