Blood Damage Analysis of ECMO Centrifugal Pump Based on CFD
Based on CFD software, the flow field of ECMO centrifugal blood pump is numerically simulated, the head characteristics of blood pump under different flow rates are calculated, the pressure, velocity and shear stress distribution of blood flowing through the impeller are studied, the cor/responding cloud images are obtained, and the effects of velocity and shear stress on blood damage are analyzed. The results show that the head curves of different flow rates coincide approximately, and all meet the requirements of blood pump parameters. When the flow rate of blood pump is lower than 6m / s, the volume fraction is 92.8%, and the volume fraction in the area with shear stress of 0-150pa is 97.95%. The blood damage of pump is small and hemolysis is not easy to occur.
