Fifth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2007)
The work deals with the numerical solution of
2D unsteady compressible viscous flows in a symmetric
channel for a low inlet airflow velocity. The
unsteadiness of the flow is caused by a prescribed
periodic motion of a part of the channel wall with large
amplitudes, nearly closing the channel during the
oscillations. The flow in the channel can represent a
simplified model of airflow coming from the trachea,
through the glottal region with periodically vibrating
vocal folds to the human vocal tract.
Index Terms. Navier-Stokes equations, unsteady compressible viscous flow, FVM, ALE method, CFD.
