A Numerical Analysis on the Hemodynamic Characteristics in the blood vessel with Stenosis

협착부가 존재하는 혈관의 유동 특성에 관한 수치 해석적 연구

Hemodynamics behavior of the blood flow is influenced by the presence of the arterial stenosis. If stenosis is present in an artery, normal blood flow is disturbed. In the present study, characteristics of steady and pulsatile flow of non-Newtonian fluid, the effects of stenosised geometry are analyzed by numerical simulation. One interesting point is that non-symmetric solutions were obtained at severity stenosis, although the stenosis and the boundary condition were all axisymmetric.
