Numerical simulation of confined pulsating jets in human phonation

Confined pulsating jets in simplified two-dimensional models of the larynx are considered to study human phonation. The jets are generated by periodically oscillating inlet velocities in stationary vocal tracts. The jets are computed by solving the 2D compressible Navier–Stokes equations by a high order finite difference method, which has been constructed to be strictly stable for linear hyperbolic and parabolic problems. Vortex dynamics is investigated.
