Abstract

A rotational shear stressor has been developed that could load the shear with the average shearing velocity of from O.to 15, 000/sec in order to clarify the quantitative relationship between the flow shear and the hemolysis. To collapse the flow behavior in this apparatus, the flow visualization was conducted with using particle tracking velocimetry to quantify the velocity, the turbulent intensity, the shearing velocity and the shear stress. As a result, it was found that the flow transited from the laminar Couette flow to the flow with some fluctuation that has the gentle core flow region and the boundary flow region with the average shearing velocity threshold of from 7, 400 to 9, 200/sec.
