Numerical Approximations of Flow Induced Vibrations of Vocal Folds

Popis výsledku v původním jazyce

The paper is interested in numerical modelling of incompressible channel flow interacting with elastic part of its walls simulating vocal fold oscillations. The flow in moving domain is described with the aid of the Arbitrary Lagrangian-Eulerian method and governed by the 2D incompressible Navier-Stokes equations. The flow model is coupled with the structural motion modelled by an aeroelastic two degrees of freedom model of the oscillating vocal folds. The described fluid-structure interaction problem is discretized in time and space. The numerical results of a channel flow modelling the glottal region of the human vocal tract including the vibrating vocal folds are shown. The vibrations of the channel walls are either prescribed (1st case) or inducedby the aerodynamical forces (2nd case).
