The aim of this study is the evaluation of the fluid dynamic characteristics regarding the blood compatibility of a centrifugal artificial pump developed by Sun Medical Technology Research Corp. Visualized sections were the centrifugal vane, the inducer and the transition regions, and outlet region. 4time-step tracking method and spring model method were used for particle tracking velocimetry. Smooth flow around curved vanes, sufficient shear flow around shaft and steady flow with low shear in the outlet were verified through the present study.
