Original abstract
A numerical model of aerosol transport in human airways is presented that contains 6 to 9 bifurcations and about 100 terminations. The model was acquired from a CT scan of a living person and contains oral/nasal cavity, and thoracic and lower airways. Two breathing activities are modeled: 1) Resting conditions with a tidal volume 0,5liter, the minute ventilation 15 l/min and the period 4 sec/cycle and 2) Heavy activity (maximum exercise) with the tidal volume 3.33 liter, the minute ventilation 120 l/min and the period 1.25 sec/cycle. The inspiration/expiration cycle was modeled following the sinusoidal function.
