... interaction between the bronchiole and the alveolus by studying a variety of cases wherein the flow complexity is progressively increased from case to case. We find that for only certain cases are the conditions for particle deposition satisfied. In contrast to the spherical cap geometry considered...

... particles ≥ 4 μ m is dominated by gravitational settling and shows little effect of fluid advection. Additionally, small and midsize particles deposit at about two-thirds height in the alveolus irrespective of the gravitational orientation whereas the deposition of large particles is governed primarily...

...J. B. Wang; Alvin C. K. Lai Particle deposition and transport in human airways is frequently modeled numerically by the Lagrangian approach. Current formulations of such models always require some ad hoc assumptions, and they are computationally expensive. A new drift-flux model is developed...
