Abstract
Fluid flow from high-frequency, low-tidal-volume ventilation has been numerically simulated in the first six generations of the bronchial tubes of the human lung, and the resulting time-varying shear stresses at the air-mucus interface were computed. One asymmetric, 5.0 Hz, 150 ml tidal volume high-frequency ventilation cycle was used as the transient boundary condition at the trachea entrance. The finite element method and the FIDAP computational fluid dynamics package were used to obtain the solution. Results indicate preferred flow proximal to the trachea, areas of recirculation, and time-averaged expiratory shear stresses at the air-mucus interface.
