Abstract

Atherosclerosis is the narrowing of the blood vessels due to the deposition of atherosclerotic plaque. Hemodynamic parameters play a critical role in the development and advancement of this cardiovascular diseases (CVDs). This paper presents the effect of bifurcations on the blood flow through left coronary artery. An idealized 3D geometry of left coronary artery is used to investigate the possible effect of flow paraments such as velocity and pressure in the vicinity of arterial walls. The effect of bifurcating angle and distance between bifurcation was examined and quantified to study the blood flow through the bifurcations and its effect. The results shows that the wall shear stress (WSS) increases near the bifurcations due to flow recirculation. In the narrow artery, the effect of WSS is observed to be high.
