On Influence of Vocal Fold Size to Frequencies of Induced Vibrations

Abstract

The paper deals with modelling of fluid-structure interaction (FSI). Particularly it is concerned with the example of human vocal folds and their vibration under excitation by the fluid flow. The vocal folds are described as an elastic body with the assumption of small displacements and therefore the linear elasticity theory is used. The viscous incompressible fluid flow is considered. For the purpose of the numerical solution the arbitrary Lagrangian-Eulerian method is used. The whole problem is solved by the finite element method based solver. The numerical results of the influence of vocal folds dimensions are presented.
