The numerical simulation of human phonation
Original language description
The talk will focus on the numerical simulation of the flow induced sound generated by the vibration of vocal folds. The two-dimensional fluid-structure interaction problem is modelled with the aid of linear elastic problem coupled to the incompressible Navier-Stokes equations in the arbitrary Lagrangian-Eulerian form. The propagation of sound sources is described by the Lighthill acoustic analogy and the Perturbed Convective Wave Equation method. All partial differential equations, describing the elastic, fluid and acoustic subproblems, are solved by the finite element method. Particularly, for the most difficult part of computation - fluid flow simulation, the modified streamline-upwind/Petrov-Galerkin stabilization is used and the different flow inlet boundary conditions are discussed. Numerical results of frequency spectra for phonation of vowel [u:] are presented.
