【 摘 要 】

Computational fluid dynamics/discrete element method (CFD-DEM) model was used to investigate the microscopic motion law of blood cells in a blood pump. The macro-hydrostatic performance indexes of the blood pump, as well as the characteristics of motion, collision. Result showed that collision among the blood cells mainly occurred at the front guide and the back guide, and the collision rate between the blood cells and the wall surface was 2.3 times the collision rate among the blood cells at the front guide vane area of the vane rotor.
