Abstract

For a blood pump, the injury to blood is a very important index of its performance. The strongly swirling turbulent flow in the internal flow field of a high-speed spiral blood pump(HSBP), is one of important factors leading to the fragmentation of the red blood cell(RBC) and the hemolysis. The study on the turbulent injure principle of blood in the HSBP is carried out by using the theory of the turbulent flow field and the hemorheology. The determinant gist on RBC turbulent fragmentation is obtained. The turbulent flow in the designed HSBP have been simulated and analyzed by using the multiphase suspend body CFD simulation technology. The simulation results indicate that the turbulence in the designed HSBP can meet the requirements of blood physiology.
