| Abstract in different language: | Numerical modelling of some vocal folds (VF) pathologies can be realized by varying properties of VF layers. The aim of this paper is to show how damping of superficial lamina propria (SLP) affects vowel production in the finite element (FE) model of the VF self-sustained oscillation with fluid-structure-acoustic interaction. Fluid flow and structure domain was solved separately in program system ANSYS. The 2D FE model features several phenomena present during human phonation: compressible unsteady viscous flow modelled by Navier-Stokes equations, setting to a pre-phonatory position, large deformations of the VF, their closure and excitation by lung pressure. The fluid mesh was deformed according to the VF motion using Arbitrary Lagrangian-Eulerian algorithm. |
