摘要
将格子Boltzmann方法应用于模拟真实人体颈动脉分叉的脉动流场,比较了不同几何形状(如动脉窦、分叉角和颈内动脉弯度)的血管中脉动流场的速度,压强以及壁面切应力分布情况,指出血管中容易发生动脉粥样硬化的部位,从而揭示动脉粥样硬化的形成和发展的血流动力学因素.
The lattice Boltzmann method was used to simulate pulsating flow field in real human carotid bifurcations. The distribution of velocity, pressure and wall shear stress were investigated under different geometric variations of carotid sinus, bifurcation angel and internal carotid artery tortuosity during a cardiac cycle. Areas prone to atherosclerotic plaque formation could be located, providing some hemodynamics basis to explain blood vessel lesion and atherosclerotic plaque formation.
