该文采用浸入式边界法(IBM),以日本理化研究所Sugiyama[1,2]的程序为平台,模拟了多个血小板在血管狭窄处的聚集过程。采用厚度由忽略不计的超弹性膜包裹的黏性液滴模拟细胞。数值模拟结果表明:血小板在聚集过程中同时受到了粘附力、聚集力和流场力的影响;红细胞体积比和硬度的增加,都会增强血小板在狭窄血管中的聚集。 In this paper, Immersion Boundary Method (IBM) was used to simulate the aggregation process of multiple platelets in vascular stenosis by using the program of Sugiyama [1,2] of the Japan Institute of Physical and Chemical Research. Cells were mimicked with sticky droplets of a thickness that was neglected by the super-elastic membrane. The results of numerical simulation show that platelets are affected by the adhesion force, the aggregation force and the flow force at the same time. The increase of volume ratio and hardness of red blood cells enhances the aggregation of platelets in the stenosed blood vessels.
