在本文的第一部分中，我们建立了一些方程来近似地描述不可压缩流体通过轴对称辐散管的流动特性。在第二部分中，描述了研究这些流动特性的实验方案，比较了理论和实验结果，并对它们在闭塞性血管疾病中的意义进行了一些推测。构造了一个塑料聚散管来确定整个狭窄的分离点和再附着点以及压降。实验中使用了水和血。获得了这些流体的雷诺数高达约1000的数据。水和血的实验结果相差不大，但总的来说，实验结果和理论结果只有相当的一致。
In Part I of this communication, equations are developed to approximately describe the flow characteristics of an incompressible fluid through an axisymmetric converging-diverging tube. In Part II, an experimental program to study some of these flow characteristics is described, the theoretical and experimental results are compared, and some speculations are made on their implications in occlusive vascular disease.A plastic converging-diverging tube was constructed to determine the separation and reattachment points and the pressure drop across the entire stenosis. Water and blood were used in the experiments. Data were obtained for these fluids for Reynolds numbers up to approximately 1000. The experimental results obtained for the water and blood did not differ greatly, but in general only fair agreement was found between the experimental and theoretical results.
