To establish quantitative, efficient design theories for centrifugal blood pumps, computational fluid dynamics (CFD) analyses were compared to the results of flow visualization tests and hemolysis tests, mainly on the Nikkiso centrifugal blood pump. The results turned out to coincide in the velocity vector plots. CFD analysis revealed that the smaller the gap is, the greater the shear stress becomes. This tendency becomes even greater with a radial gap change. Hemolysis study also indicated that the smaller the gap is, the greater the hemolysis. CFD analysis in comparison with hemolysis tests could be a useful index for developing blood pumps in the future.
为建立离心式血泵的定量、高效设计理论，主要针对日机装离心式血泵，将计算流体动力学（CFD）分析结果与流动可视化测试及溶血测试结果进行了比较。结果表明，速度矢量图中的结果是一致的。CFD分析显示，间隙越小，剪切应力越大。随着径向间隙的变化，这种趋势更加明显。溶血研究也表明，间隙越小，溶血越严重。与溶血测试相比，CFD分析可能是未来开发血泵的一个有用指标。
