Coherent structures in the flow inside a model of the human vocal tract with self-oscillating vocal folds

Original language description

The measurement of the airflow in a specially developed 1:1 scaled complex physical model of the voice production is described. This model consists of simplified models of the trachea, the self-oscillating vocal tract with acoustical spaces that correspond to the vowel [a:]. The measurement set-up enabled to use the Particle Image Velocimetry (PIV) method for description of the airflow-pattern and synchronous vocal fold vibration visualization, acoustic and pressure measurements. The results are presented for the subglottal pressure and airflow rates in the range of normal human phonation. Especially, Coanda effect of the glottal jet and coherent structures showing large eddies in the glottal region of the vocal tract are studied.
