dc.description.abstractArticle deals with numerical simulations and its verification by experiments in trachea of idealized geometry of tracheobronchial airways by using unsteady RANS approach. Respiratory cycle was simulated by sinusoidal function under period of 4 seconds and tidal volume of 0.5 litres of air which corresponds to breathing under resting condition. Results was compared with experiments measured by laser-Doppler velocimeter in eight points on four cross sections on trachea. Model consists of mouth cavity, larynx and tracheobronchial tree up to fourth generation of branching.en
