Abstract Flow behavior at the arterial bifurcations has significant implications on the plaque formation. It depends on the vessel size, two bifurcation angles, i.e. angle between the mother and daughter vessels and their relative magnitudes. In this study, hemodynamics for steady and pulsatile flow of blood has been investigated in an idealized carotid artery bifurcation having all the vessels in the same plane for a range of bifurcation angles for symmetric and asymmetric bifurcation. The simulations reveal the presence of a pair of helical vortices, symmetric about the bifurcation plane, in each daughter tube near the bifurcation.

不对称对理想化动脉分叉处流动行为的影响

摘要 动脉分叉处的流动行为对斑块形成有重要影响。这取决于血管大小、两个分叉角，即母血管和子血管之间的角度及其相对大小。在这项研究中，在理想化的颈动脉分叉处研究了血液稳定和脉动流动的血流动力学，所有血管都在同一平面上，对称和不对称分叉的一定范围的分叉角度。模拟结果表明，在靠近分叉处的每个子管中，存在一对关于分叉平面对称的螺旋涡流。
