This paper describes a computational prediction method for hemolysis and thrombus properties in orifice-pipe blood flows. In this study, several types of orifice-pipe flows by using two turbulence models are computed, to which k-ε model with partly patched Launder-Kato model (LK-Zonal model) to improve computational accuracy. Using these database, quantity of hemolysis and thrombus is predicted by estimating (1) turbulent shear stress and (2) transport of concentration of blood coagulation factor. It is concluded that there were possibilities to predict thrombus in the orifice pipe flow, using concentration of blood coagulation factor.
