Effects of Inlet and Outlet Conditions on Fluid-Wall Interaction Models in Hemodynamics

Abstract

To study effects of different inlet and outlet conditions on fluid-wall interaction models in hemodynamics. The finite element method was employed. According to different inlet and outlet conditions, several groups were divided and numerical experiments were done. The distributions of blood flow velocity are blunt; the blood pressure changes are different, and reflection is presented in a certain pressure waveform; the stresses and strains of blood vessel wall are caused by the blood pressure and they reflect the change trend and waveform of the pressure. The effects of inlet and outlet conditions on fluid-wall interaction models in hemodynamics are significant and the conditions can affect flow field distributions.
