  • Flow visualization for a high-speed full-scale model of hydrodynamic levitation blood pump

抄録

The aim of this study is the fluid dynamic evaluation of a hydrodynamic levitation centrifugal pump developed by AIST. Since the Pump has a hydrodynamic bearing rotating at 1900rpm, we introduced a new high-speed visualization systems with Double-pulse YAG laser. Visualized sections were the impeller, and outlet regions. The result of flow visualization showed good correlation with animal experiment and CFD.
