Separated flow behavior in an in-vitro rigid model of the laryngeal channel

Résumé

Flow through an in-vitro rigid model of the laryngeal channel is measured using pressure sensors, and visualized using the Schlieren technique for different geometrical configurations. A quasi-impulsive upstream flow condition is used to simulate the jet emerging from the glottis at phonation onset. The separated flow behaviour in the presence of a ventricular constriction ("false vocal folds") is examined. Direct numerical simulations are proposed to assess the aerodynamic effects of the ventricular bands on the dynamics of the flow patterns involved.
