Originální abstrakt
The flow induced self/oscillation of the human vocal folds in interaction with acoustic processes on the simplified vocal tract model was explored by 3D FE model. Developed FE model includes vocal folds pretension before phonation, large deformations of the vocal tissue, vocal folds contact, fluid-structure interaction, morphing the fluid mesh according the vocal folds motion (ALE approach), unsteady viscous compressible airflow described by the Navier-Stokes equations and airflow separation during the glottis closure. Iterative partitioned approach is used for modelling the fluid-structure interaction. Computed results prove that the developed model can be used for simulation of the vocal folds self-oscillation and resulting acoustic waves. The developed model enables to numerically simulate an influence of some pathological changes in the vocal fold tissue on the voice production.
