Abstrakt: A mechanical lung model with branching up to five generations, developed from an actual human lung, is used to study experimentally the velocity profiles in the trachea and the main branches. Three different flow rates representing light, medium, and heavy breathings have been simulated for both inhalation and exhalation. The velocity profiles, except for the one in the trachea in the frontal direction due to exhalation, are in good agreement with the velocity profiles in simplified models of published literature.
