| Research Abstract |
The present study deals with suppression of cavitation in blood pump s used in extracorporeal circulation. The cavitation performances of the centrifugal pump with a two-stage impeller, developed in the investigators' collaboration, were investigated and compared to those of the commercially available blood pumps. The results were effectively utilized in the modification of the centrifugal pump to achieve higher resistance to cavity generation as well as destruction of the blood cells. The prototype of the modified model was fabricated, which demonstrated sufficient hydraulic performances as predicted by the numerical models established through this study.
