Velocity and shearing velocity near the volute casing wall in several geometry models of a centrifugal blood pump was quantified by particle tracking velocimetry where higher shear is likely to occur since higher shear has a close relationship with higher hemolysis. As a result, the measurement results of the particle tracking velocimetry were well corresponded with the results from the computational fluid dynamic analysis. Then, averaged shearing velocity powered was correlated with the hemolysis index of the pump.
