Query: Computational Fluid Dynamic Simulations In a Model of a Carotid
  Bifurcation Under Steady Flow Conditions   Strokes are still one of the leading causes for death after heart diseases
and cancer in all over the world. Most strokes happen because an artery that
carries blood uphill from the heart to the head gets clogged. Most of the time,
as with heart attacks, the problem is atherosclerosis, hardening of the
arteries, calcified buildup of fatty deposits on the vessel wall. The primary
troublemaker is the carotid artery, one on each side of the neck, the main
thoroughfare for blood to the brain. Only within the last 25 years, though,
have researchers been able to put their finger on why the carotid is especially
susceptible to atherosclerosis. In this study, the fluid dynamic simulations
were done in a carotid bifurcation under the steady flow conditions
computationally. In vivo geometry and boundary conditions were obtained from a
diseased who has both sides of stenosis located in his carotid artery patients.
The location of critical flow fields such as low wall shear stress (WSS),
stagnation regions and separation regions were detected. Low WSS was found at
the downstream of the bifurcation.
