开发了计算流体动力学（CFD）模型，并用于模拟与脉动呼吸导管相关的血流。本CFD研究的主要目标是评价球囊产生的流体如何渗透通过纤维束并与通过导管的流体相互作用。模拟结果表明，尽管纤维束周围的流型不均匀，但纤维束内部的流动在纵向和周向上都是均匀的。因此，纤维束内的流动条件对于血液氧合过程保持最佳。结果表明，纤维束周围的分流随着球囊脉动率的增加而减少。
A computational fluid dynamic (CFD) model was developed and used to simulate blood flow associated with our pulsating respiratory catheter. A principal goal of this CFD study was to evaluate how the balloon-generated flow permeated through the fiber bundle and interacted with the flow past the catheter. The simulation showed that the flow inside the fiber bundle was uniform longitudinally and circumferentially despite the nonuniform flow patterns around the bundle. Thus, the flow conditions inside the fiber bundle remained optimal for the blood oxygenation process. The results indicate the shunt flow around the fiber bundle decreased with increasing balloon pulsation rate.
