Fluid-structure-acoustic interaction problem in modelling of human vocal folds vibration
Original language description
This paper studies vibroacoustic sound produced by self-oscillating human vocal folds model as one of major sound source responsible for human phonation. The human phonation is a complex phenomenon described by interaction of three physical fields - elastic body deformation, fluid flow and acoustics, and their mutual couplings. Therefore it is sometimes referred as fluid-structure-acoustic interaction (FSAI) problem. Here we present FSI problem modelled by linear elasticity theory (vocal fold) and the viscous incompressible airflow modelled by Navier-Stokes equations due to typical low flow velocities of small Mach number. The arbitrary Lagrangian-Euler method (ALE) for the purpose of numerical simulation of the time varying computational domain is applied. In order to model one sound source mechanism of the human phonation the vibroacoustic problem is solved in larger acoustic domain including vocal tract model. The sound source considered in this model is the normal acceleration of the vibrating vocal folds boundary. The numerical models are based on the finite element method. The results of vibroacoustic problem are shown and analyzed.
