Originální abstrakt

Validation of numerical simulation using experimental data is necessary prerequisite for authentication of proper use of numerical method. This article deals with comparison of velocity vectors on idealized model of human upper airways during stationary inspiration for three different breathing regimes. For the purpose of this study, the model which includes realistic geometry of mouth cavity and glottis coupled with idealized geometry of trachea and bronchial tree up to fourth generation of branching was made. Calculations were compared with experiments performed by using of Phase-Doppler Particle Anemometry (P/DPA) on identical geometry. Velocity data was compared at several points in trachea and bronchial tree. Specific air flow characteristics are documented and discussed based on results of the numerical simulation of the velocity field.
