Abstract

The paper presents the study results of the impact of the common carotid artery bifurcation angle on the flow disorders. The studies were carried out using numerical methods. Based on actual images, geometry was made of the diffuser channel with bifurcation and predetermined angle. The flow simulation results showed that for bifurcation angles exceeding 60° the vortices near the bulb start to occur—at that time almost a double increase of the parameter values takes place, related to flow disorders. The vortex becomes increasingly larger and grows proportionally to the value of the bifurcation angle. Thanks to the studies carried out, three areas have been shown, in which plaques may deposit, due to disadvantageous geometry. Based on the simulation results, arteries have been divided into three groups of risk. It has been proven that bifurcations exceeding 50° significantly disturb the flow and the points of whirlpool occurrence represent frequent points of plaque depositions.
