Overview

Computational fluid dynamics reveals flow disturbances and low wall shear stress in aortic bifurcation, posing risks for endothelial dysfunction and atherosclerotic plaques.

Key Points

  • Investigate blood flow characteristics in aortic bifurcation to understand hemodynamics influencing atherosclerosis.
  • Used a three-dimensional model of human aortic bifurcation
  • Employed computational fluid dynamics to simulate blood flow
  • Applied Navier–Stokes equations and Carreau–Yasuda model for non-Newtonian blood
  • Assessed hemodynamic parameters like velocity, pressure distributions, and wall shear stress.
  • Identified complex flow features such as separation and recirculation zones
  • Showed areas of low and oscillatory wall shear stress
  • Associated low WSS with endothelial dysfunction and atherosclerotic plaque formation
  • Demonstrated CFD as an effective non-invasive diagnostic tool.
