Abstract
In the paper a mathematical model of airflow in human vocal folds is presented. The geometry of the glottal channel
is based on measurements of excised human larynges. The airflow is modeled by nonstationary incompressible
Navier-Stokes equations in a 2D computational domain, which is deformed in time due to vocal fold vibration.
The paper presents numerical results and focuses on flow separation in glottis. Quantitative data from numerical
simulations are compared to results of measurements by Particle Image Velocimetry (PIV), performed on a scaled
self-oscillating physical model of vocal folds.
