Optimizing the design of a pediatric blood pump through orthogonal experimentation

This study investigates the correlation between blade parameters and hydraulic performance in axial flow pumps used for blood pumping. The results of both flow field analysis and experimental studies, conducted using orthogonal experiments, demonstrate that the optimized blood pump exhibits enhanced performance in reducing both reflux rate and shear stress. These findings provide valuable insights for the design optimization of pediatric ventricular assist devices.
