Starting jet airflow is investigated in a channel with a pair of consecutive slitted
constrictions approximating the true and false vocal folds in the human larynx.
The
flow is visualized using the Schlieren optical technique and simulated by
solving the Navier-Stokes equations for an incompressible two-dimensional
viscous flow. Laboratory and numerical experiments show the spontaneous formation
of three different classes of vortex dipolar structures in several regions of the
laryngeal profile under conditions
that may be assimilated to those of voice onset
