Dynamic model of process of the air passage through the nasal cavities
Abstract
The analysis of the aerodynamic processes occurring in the nasal cavities and determining the basic respiratory function of the upper respiratory trajectories is made. The difference in phase between the periodically alternative exterior pressure and the airflow inside simulated nasal airway is established. The relation between energy dissipation of airflow as a coordinate function and frequency of respiration is determinate. Is shown, that at a small frequency of respiration the maximum of the respiration power dissipation is on-axis of the nasal airway, and with diminution of frequency is displaced in the nasal wall.
