Název v původním jazyce
Numerical simulation of the vocal folds self-oscillation in interaction with the human 3D FE vocal tract model
Popis výsledku v původním jazyce
Finite element (FE) model of flow induced oscillations of the human vocal folds in interaction with acoustic processes in a simplified 3D FE vocal tract model is presented. The FE model includes vocal folds pretension before starting phonation, large deformations of the vocal fold tissue, vocal folds contact, fluid-structure interaction, morphing the fluid mesh according the vocal folds motion, unsteady viscous compressible airflow described by the Navier-Stokes equations and airflow separation during the glottis closure. The developed model enables to study influence of some pathological changes in the vocal fold tissue on voice production. After a FE mesh refinement, the model cal be also used to simulate stresses that can result in tissue damages causing various voice disorders.
