Comparing the Use of Compressible and Incompressible Flow in the FE Mode lof Human Vocal Folds Self-oscillation
Original language description
In this study a three-dimensional (3D) finite element (FE) model of the flow-induced self-oscillation of the human vocal folds in interaction with air in a simplified vocal tract model is presented. The 3D vocal tract model of the acoustic spaces for Czech vowel [a:] was created by converting the data from the magnetic resonance images (MRI). The developed FE model includes fluid-structure interaction, morphing the fluid mesh according to the vocal-fold motion, unsteady viscous compressible/incompressible airflow described by the Navier-Stokes equations, airflow separation during the glottis closure, large deformations of the vocal-fold tissue and vocal-fold contact. The aim of this work is to analyze the effect of compressible and incompressible flowmodel on produced air pressure fluctuations and on vibrations of the vocal folds using the identical FE mesh and boundary conditions.
