Determination of nasal resistance according to CT data

Abstract

The principal nasal airflow regime is turbulent, in which the logarithmic velocity profile at typical flow rates is set at about half the length of the nasal cavity. The analysis of the configuration of the nasal cavity showed that the most common local disturbance of the airflow in the nasal passages is the resistance of the "latch" and "turn of the flow" type, caused, as a rule, by the presence of local curvature of the nasal septum.
