Aeroacoustic simulation of human phonation based on the flow-induced vocal fold vibrations including their contact

Original language description

This paper deals with the numerical simulation of the flow induced sound as generated in the human phonation process including vocal folds (VF) contact. The hybrid approach is used allowing to separate the acoustic and the biomechanical description of the considered problem. The two-dimensional fluid-structure interaction (FSI) problem is modelled by a simplified linear elastic model coupled to the incompressible Navier-Stokes equations in the arbitrary Lagrangian-Eulerian form and special attention is paid to the treatment of the contact problem in the FSI context. Following approach of [Sv & aacute;& ccaron;ek and Hor & aacute;& ccaron;ek, 2021] the incompressible flow model is modified by an addition of fictitious porosity term and the penalization inlet boundary condition is used. Further, the Lighthill acoustic analogy is applied for calculation of sound sources and their propagation through a vocal tract model. All partial differential equations, describing the elastic body vibration, the fluid flow and the acoustics, are approximated by finite element method. Numerical results of one-sided vocal fold paralysis are presented.
