Visualization of thrombus formation and CFD based prediction on shear flows

摘要

This paper describes development of the prediction method of thrombus formation by Computational Fluid Dynamics (CFD) on pipe orifice shear flows. These shear flows are typical models of the flow in the rotary blood pump. In this investigation, the thrombus formation in blood plasma flow is visualized, and normal FDM (Finite Difference Method) and modified lattice Boltzmann method are used to predict the backward forwarding step flow, that is simple model of the orifice flow.
