Numerical Approximation of Flow Induced Vibration of Vocal Folds
Original language description
In this paper the numerical study of a simplified model of airflow through glottal region of human vocal tract is addressed and the self-oscillating vocal fold is modelled. The main attention is paid to comparison of approximation of a coupled fluid-structure interaction problems to results of published aeroelastic model. In order do compare these approaches a simplified geometrical domain is considered. Previously, the aeroelastic problem was modelled as 1d flow, which allows to determine flutter boundary (i.e. flow velocity for which the instability occurs followed by the vocal folds self-oscillations creating the human voice source). Here, a more general model is developed, the airflow through two-dimensional channel interacts with vibrations of channel walls induced by aerodynamical forces. The mathematical model is described by the airflow governed by the incompressible Navier-Stokes equations. The structure vibrations are described with the aid of two-degrees of freedom model.
