... progression. In turn, we combine computational fluid dynamics (CFD) approach and simultaneously employ CT scans to obtain air flow patterns within the human trachea. This essentially requires enforcing idealized profiles, i.e., flat, parabolic, or Womersley, which, in the event of limited clinical data, can...

... (CTA) images, and hemorheological parameters including time-averaged wall shear stress (TAWSS), oscillatory shear index (OSI) and relative residence time (RRT) were analyzed by computational fluid dynamics (CFD). The results showed that iliac vein stenosis could significantly increase the wall shear...
