The glottis is the 3-D space between vocal folds that changes dynamically during phonation. The laryngeal flow through the glottis provides the driving forces on vocal folds.
Vocal folds oscillate to modulate the airflow.
The dynamics of motion depends on tissue characteristics, initial positions and air pressure distributions in the glottis. Another driving force is the shear force from air viscosity near the surface, which is determined by velocity distribution in the glottis, and hence the present studies. The aim of this project is to simulate the laryngeal flow through a model glottis of given dimensions. A computational model that predicts the pressure and velocity distributions in the given model of the glottis is developed and studied. The laryngeal flow is simplified as a 3D flow with constant span wise opening.
