Simulation of Blood Flow in Human Aorta including Thirteen Main Arteries (eccomas Cfd 2010)

This paper investigates the mechanical properties of blood flow in main arterial system of human. The system includes aorta, subclavian, mesosentric, iliac artery, renal artery, celiac artery. The geometric domain of artery network is obtained using a real patient data. As an input, Womersley velocity profile [2] is used. Combination of thirteen arteries with aorta gives better understanding of the interactions of blood flow among the arteries. For example, the effect of a narrowing region at the iliac artery to the flow at aorta or renal artery can be studied with the help of the model presented. Results of the study include velocity, pressure and WSS (Wall Shear Stress) distributions at the arteries and the bifurcation regions of the arterial tree [1, 3]. Later, regional domains are inter-examined and dynamics of the system is compared within the thirteen branched model results. E. Aribas, S. Piskin and M.S. Celebi
