A Fluid-Structure Interaction Based Numerical Investigation on the Outlet Condition of Artery Basic Model

Abstract:

Improving the numerical model of the hemodynamic is very meaningful to analysis the formation aneurysm, to predict the rupture risk and to provide operation plan. But the outlet boundary conditions are mostly determined pressure or velocity. So it is important to consider the transmission load of the outlet in the numerical simulations of the hemodynamic. Then we choose the porous media to approximate simulate the transmission load. We simulated a case with transmission load and a case without transmission load as the matched group. The result showed that the second pressure wave could only exist in the case with the transmission load, and the pressure range of the case with transmission load was more physiological. And there were evidences of the coupling relationship between the FSI blood flow to the transmission load. So it is necessary to consider the transmission load in the Blood flow dynamics problems.
