Finite Element Modeling of Airflow During Phonation
Original language description
The airflow in vibrating vocal folds is modeled by incompressible non-stationary Navier-Stokes equations in 2D, which are numerically solved by the finite element method (FEM). The computational domain changes in time therefore the equations are reformulated using Arbitrary Lagrangian-Eulerian (ALE) approach. To validate the results from the mathematical model, a self-oscillating physical model of vocal folds was measured. The computational results compare well with the experimental data in maximum glottal jet velocity, location of major vortex structures and overall flow dynamics.
