Originální abstrakt

The air flow in a realistic geometry of human lung extended of mouth cavity is simulated with computational flow dynamics approach as stationary inspiration. Geometry used for the simulation includes mouth cavity, larynx, trachea and bronchial tree to the seventh generation of branching. Unsteady RANS approach were used for the air flow simulation. Velocities corresponding to 15, 30 and 60 l/min of flow rate were set as boundary layer at the inlet to the model. These flow rates are frequently used for representation of human activity with context of breathing. Physical phenomenons in various part of model during this different flow rates were discussed with respect for future investigation of particle deposition.
