摘要：Computational Fluid Dynamics (CFD) has been used for developing and evaluating a novel axial flow blood pump. The pump embodiment includes two counterrotating impellers with independent motorization. This device could be used as an implantable pump for boosting blood circulation in patients whose hearts are not pumping at an adequate cardiac output. The blood pump was designed for a flow rate of 5 L/min and 100 mmHg of head pressure and a combination of counter-rotational speeds of 8400 rpm and 3900 rpm for the inlet and outlet impellers respectively. From the CFD results it is concluded that an embodiment including two counter-rotating impellers is hydraulically feasible.
