Abstract :
Continuous flow rotary blood pumps have been developed for decades due to the limited heart donors. Both axial and centrifugal flow types have been developed. In this study, an axial flow blood pump is studied, and the main focus is on the impeller optimization. Totally, nine impeller designs have been studied. It has been found that both the blade height and wrap angle of the impeller affect the hydraulic and hematological performances.
