Thoratec HeartMate III的流体动力学(Thoratec Corp.，Pleasanton，CA，U.S.A.)在一系列生理操作条件下对左心室辅助装置进行分析。HeartMate III是一种带有磁悬浮转子的离心式流量泵。采用计算流体动力学(CFD)分析和实验颗粒成像流动显示(PIFV)技术对整个泵进行了分析。CFD预测与实验成像的比较显示出很好的一致性。CFD和实验PIFV都证实了HeartMate III泵主要部件：进气口、蜗壳和出口的良好流场。在整个运行范围内，HeartMate III显示出清洁的流动特性和良好的表面清洗性能。
The fluid dynamics of the Thoratec HeartMate III (Thoratec Corp., Pleasanton, CA, U.S.A.) left ventricular assist device are analyzed over a range of physiological operating conditions. The HeartMate III is a centrifugal flow pump with a magnetically suspended rotor. The complete pump was analyzed using computational fluid dynamics (CFD) analysis and experimental particle imaging flow visualization (PIFV). A comparison of CFD predictions to experimental imaging shows good agreement. Both CFD and experimental PIFV confirmed well-behaved flow fields in the main components of the HeartMate III pump: inlet, volute, and outlet. The HeartMate III is shown to exhibit clean flow features and good surface washing across its entire operating range.
