| 1. | In this paper a kind of cardio - cerebral arterial bifurcation vessel hemodynamic characteristics are studied with the boundary element method , and the blood flowing velocity vector distributions have been calculated . in addition , the flow field distribution and the pressure on the particle surface are also calculated , when there is flow - round particle at the place of bifurcation , the move tendency of the particle is judged , the possible reasons of causing the atherosclerosis , thrombus , angioma are analysed
本文用边界元方法研究了一类典型心脑动脉分支血管中血液流动的流体动力特性,计算了分支血管血液流动的速度矢量分布,同时计算了分支附近有多个颗粒状绕流物时血液的流场分布,及颗粒物所受压力状况,给出了颗粒物的运动趋势,分析了引起粥样斑块病变、血瘤、血栓的可能原因 |
