Flow and acoustic effects in the larynx for varying geometries
Original language description
Aeroacoustic phenomena are the main contribution to the human voice production process and the aim is to achieve a better understanding of this process by means of numerical simulation. A hybrid numerical approach is thereby used, decoupling computational flow dynamics (CFD) from computational aeroacoustics (CAA). In a first stage the airflow through the larynx with oscillating vocal folds is simulated. In a second stage the acoustic sources are determined and finally the propagation of the acoustic waves, by means of a perturbation approach. The developed tool is capable of analysing different scenarios in voice production. Here, we investigate various glottal geometries and vocal fold oscillations. Thereby, the CFD simulations are run for four glottal opening types: a rectangular form, triangular form, a sinusoidal form and for one case a vocal fold is kept static. Thereby, we study in detail the changes in the flow, the acoustic source terms as well as the generated sound.
