形成人工血栓的Chandler圆环内的流动分析

本文应用流体力学方法对Chandler 圆环内人工血栓形成的流动情况进行了细致分析。结果表明,形成血栓的下弯月面附近是一个既有迴流,又有二次流的区域,而且迴流的中心主流冲击着弯月面,为颗粒的聚集提供了有利的条件。本文对分析与血液流动有关的人工脏器和体内血栓形成的机理有一定的价值。

Flow pattern in chandler loop - the artificial thrombus formation

In this paper a hydrodynamic approach is used to analyse carefully the flow field inChandler loop--the artificial thrombus formation. The results obtained show that near thelower meniscus where the thrombus is formed, there is a back flow accompanied with asecondary flow and its mainflow is toward the meniscus, thus providing a favourable condi-tion for corpuscle aggregation. Our finding is valuable for studying the mechanism ofthrombus formation in artificial organ and in vivo.

Chandler园环内人工血栓形成处的流动分析

<正>我们应用流体力学方法对Chandler园环内人工血栓形成处的流动情况进行了较细(?)的分析。当Chandler园环以用速度ω在铝直平面上顺时针方向旋转时,右边的下弯月面下降,左边的上弯月面下降,从而造成液面差,由此产生的压力压推动环内流体运动。
