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 κ-ε model with partly patched Launder-Kato model (LK-Zonal model) to improve computational accuracy. Using these database, quantity of hemolysis is predicted by integrating (1) turbulent shear stress and (2) principal shear stress, and (3) maximum shear stress. It is concluded that the quantity of hemolysis could not be predicted accurately, although turbulent normal stress is comparable to the turbulent shear stress.
