3D flow simulation at the geometry of thirteen main arteries of a human

Biomechanical properties of blood flow are researched in 13 main arteries of human body. 3D blood network model consists of regions such as aorta, carotid, iliac, renal and celiac sections. A real patient data is used as the geometric domain and the Womersley velocity profile is implemented as the inlet. Investigating 13 main arteries at once as a full system helps to improve the understanding of the short artery sections. Comparing the effects of velocity and flow patterns in 13 artery system shows a better understanding of biomechanical properties in dissected regions, especially at arterial branch points. The main purpose of this work is to simulate the blood flow using 13 branches of the most crucial and largest arteries in the chest and abdominal region of a human. It is thought as arteries and veins as simple tubes, so the artery is susceptible to biomechanical factors. Our focus here is arterial trees and their relation between the circulation systems which are constantly being researched in order to find substitutes clinically. Therefore, simulation in disease progression and clinical intervention are associated within artery wall mechanics. Results show that velocity, pressure and wall shear stress (WSS) distributions vary when examined with local bisections. Results also show that better representation of complex 13 artery bifurcation geometry gives more detail on the flow characteristics, hinting us the flow projections of a nozzle effect and high pressure increment at the level two bifurcation in the iliac. The narrowing of the arteries in the celiac region happens to show high speed and pressure values in the results. This is referred to as stenosis.
