By fem , the numerical simulation was carried out according to such models , many important hemodynamic variables , such as the tempo - spatial velocity field at every cross section of the artery , the pressure distribution , the secondary flow and the wss ( wall shear stress ) at the specific areas were obtained , which will help understand the biomechanics of coronary atherosclerosis furtherly . many investigators studied the stenotic artery by means of 2 dimensional models , which can only simulate the planar pulsatile waves and got , to some extent , some general results of the blood flow without considering the secondary flow and the reality of physiological conditions 本文的着眼点和研究的目的在于,希望利用在血流动力学方面的研究优势,用有限元方法对动脉粥样硬化的血流动力学问题进行数值模拟,研究动脉粥样硬化在生成和发展过程中的血流动力学、血管壁生理及生物力学性能的变化规律,以及这两种变化规律之间的相互作用与动脉粥样硬化的发生和发展的关系,通过大量算例的对比分析,以期在这方面作些基础而有实际价值的工作。
