弯曲动脉内脉动流的有限元分析
A Finite Element Analysis of Pulsatile Flow in Curved Artery
【摘要】 给出了主动脉弓内的血液流动的理论模型、边界条件;根据生理脉动流条件,对主动脉弓内血液流动进行有限元数值模拟,分析了计算结果及动脉粥样硬化的流体动力学机理.
【Abstract】 The theoretical model and boundary conditions of blood flow in the aortic arch are first given. Then according tO the conditions of physiological pulsatile flow, the finite element numerical simulation of the blood flow in the aortic arch is made. Finally, the calculated results and the fluid dynamics mechanism of atherosclerosis are analyzed.
