• 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.
