| Research Abstract |
Computational fluid dynamics (CFD) simulations were carried out for particle tracking in oscillatory flow in a 3D realistic model of the human airways constructed based on X-ray CT images. Particle tracking revealed that the direction-dependent velocity profile with flow separation at the bifurcation promotes axial fluid dispersion in the airways. It was also found that the variance of the particles increases with the increase of volume change in an expanding and contracting model of small airways.
