Structure Design and Flow Field Simulation of Magnetic Liquid Suspension Centrifugal Blood Pump
To reduce the energy consumption and blood damage of a centrifugal blood pump, this paper uses a permanent magnet bearing and blood flow pressure bearing to support blood pump impeller, design a magnetic fluid suspension centrifugal blood pump, three-dimensional numerical simulation of a magnetic fluid suspension centrifugal blood pump internal flow field, achieve the pressure of the blood pump flow channel and the velocity distribution, get the relationship between blood pressure and flow rate of the pump. The results can provide a theoretical basis for centrifugal blood pump design and improvement.
