Abstract
This paper describes a numerical prediction method for thrombus formation in orifice-pipe blood flows. In this study, several types of orifice-pipe flows by using two turbulence models are computed, which k-εmodel with partly patched Launder-Kato model (LK-Zonal model) to improve computational accuracy. Using these database, quantity of thrombus is predicted by integrating (1) transport equation for concentration of blood coagulation factor and (2) shear velocity, and (3) wall distance. It is concluded that there should be large thrombus formation region in front of the orifice and in the recirculation area.
