Abstract

The hemolytic property of the blood pump has the relationship with high shear stress near the volute casing wall. Therefore, the shear stress distribution near the volute casing wall was quantified by PIV to evaluate the hemolytic property of the centrifugal blood pump for cardiopulmonary bypass. The velocity distribution was measured by PTV, then the shearing velocity distribution and Reynolds stress distribution to calculate the shear stress distribution. As a result, the shear stress near the casing wall and the hemolysis level increased as the pump rotational speed increased. Namely, the positive correlation between the shear stress measured by PIV and the hemolysis level of the blood pump was confirmed.
