摘　　要：不同程度动脉瘤栓塞的红细胞颗粒运动状况数值模拟,应用液固两相流计算流体力学仿真,血液流动采用瞬态,血管壁采用刚性壁模拟。通过仿真计算,最终获取动脉瘤栓塞程度不同的两相流的血流状况:动脉瘤栓塞程度不同,导致动脉瘤内红细胞体积分数分布不同,血流速度分布、壁面切应力分布不同,栓塞也导致红细胞聚集现象不同。The Movement of Red Blood cell particles in different degrees of aneurysm embolization was simulated by liquid-solid flow simulation, transient blood flow simulation and rigid wall simulation, respectively. Finally, the blood flow of two-phase flow with different degrees of aneurysm embolization was obtained by simulation calculation. The different degrees of aneurysm embolization resulted in different distributions of red blood cell volume fraction, blood flow velocity and wall shear stress, embolization also causes different aggregations of red blood cells.
