Abstract

This article is devoted of study of the air flow mode in the nasal cavity during a forced breath. It is extremely necessary to know what the air flow mode for aerodynamic calculations. We calculated the area and the equivalent diameter and Reynolds numbers for pathologies with functional disorders of nasal breath and made the following conclusions. High sensitivity to changes of the Reynolds numbers of the anatomical configuration of the nasal cavity causes that when simulation of passage of the airflow through the nasal cavity is necessary to determine the pressure drop over the length and local resistances. This makes it possible to take into account the effects of the air flow friction against the walls of the nasal cavity and vortex formation on local changes of configuration in the nasal channels.
