Flow studies in a model carotid bifurcation.

摘要: Boundary layer separation in a plexiglass model carotid bifurcation was investigated relation to the origin of atherosclerotic plaque clinically found this region. Our comparable human both dimensions and geometry. Water flowed through at Reynolds numbers from 200 1200 under steady pulsatile flow conditions, with outflow external internal branches varied. The near-wall visualized by slow injection dye ports machined model. Under physiological number 500 split similar that rest, boundary occur sinus across origin, forming shell slowly moving fluid around bifurcation. rapidly mainstream impinged directly on divider. location correlates best low shear region not high Preliminary studies demonstrated little change results.
