Resumen:
Unsteady airflow is investigated in a channel with a geometry approximating that
of the human larynx. The laryngeal flow is simulated by solving the Navier-Stokes equations for
an incompressible two-dimensional viscous fluid, and visualized using the Schlieren technique in
an experimental setup consisting of a rigid replica of the larynx, with and without ventricular
bands. This study shows the spontaneous formation of vortex couples in several regions of the
laryngeal profile, and at different stages of the evolution of the starting glottal jet.
