This paper describes a numerical prediction method for hemolysis properties in orifice-pipe blood flows. In this study, several types of orifice-pipe flows by using two turbulence models are computed, which are ( 1 ) standard low Reynolds number k-ε model and (2 ) the k-ε model with partly patched Launder-Kato model (LK-Zonal model) to improve computational accuracy. These predicted flows are compared with (a) measuring pressure loss and (b) measuring reattachment length, and it is found that the flow using LK-Zonal model has good agreement with experiments. Then the hemolysis properties are estimated from the predicted flows. The results are 1) computational accuracy of orifice-pipe flow is improved by using LK-Zonal model, 2) accuracy of predicted hemolysis is also improved especially in orifice-pipe that have long contracted part.

This paper describes the particle inertia and the contact with the wall of red blood cells on the variance of particle path, that should depend on the hemolysis properties. The new methods of examining the inertia of red blood cells (particle) on particle path are discussed using computational fluid dynamics (CFD). In this method, the particles are moved by Stokes drag including effects of difference between density of plasma and internal liquid in the blood. The results of analysis by this method show that (1) the diameter of the particle (red blood cell) that means inertia of the cells, (2) the configuration of the objective wall boundary are important factor. These results also show that if the inertia and the contact with the wall are considered, the precision of the prediction of the hemolysis properties will be progressed.
