On Numerical Approximation of Uid-Structure Interactions for Interaction of Air Flow with a Model of Vocal Folds

Valášek J., Horáček J., Sváček P.

Abstract:
This paper deals with ow driven vibration of an elastic body. Our goal is to develop and mathematically describe a simplified model of the human vocal fold. The developed numerical schemes for viscous incompressible uid ow in ALE formulation and the elastic body are implemented by two solvers, specific for each domain. The studied problem is coupled by Dirichlet-Neumann boundary conditions. Both solvers are based on the finite element method. Particularly, for the uid model the crossgrid elements are used. Numerical results focus on the verification of the developed program.

Keywords:
