On Mathematical Models of Airflow in a Glottal Channel Model Periodically Closed by Flow Induced Vocal Folds Vibration
Original language description
In this paper a mathematical model of human voice creation is addressed, which is a complex process involving airflow induced vibrations of vocal folds. The vocal folds oscillations is basically a flutter type of instability. During the phonation a higher flow rates causes vibrations with increasing amplitudes, which leads to collisions of the vocal folds and to the closure of the glottis. In this paper the problem of collisions of vocal folds is addressed. The mathematical model includes a modification of the computational domain, use of an artificial porous media subdomain and a suitable modification of the inlet boundary condition. The described mathematical model is discretized and numerical results are shown.
