Blood flow dynamics in patient specific arterial network in head and neck

SUMMARY This paper shows a steady simulation of blood flow in the major head and neck arteries as if they had rigid walls, using patient specific geometry and CFD software FLUENT R . The Artery geometry is obtained by CT‐scan segmentation with the commercial software ScanIP TM . A cause and effect study with various Reynolds numbers, viscous models and blood fluid models is provided. Mesh independence is achieved through wally + and pressure gradient adaption. It was found, that a Newtonian fluid model is not appropriate for all geometry parts, therefore the non‐Newtonian properties of blood are required for small vessel diameters and low Reynolds numbers.
