Abstract :
The authors derive a model of the glottal flow which includes nonlinear flow, the dynamic generation of sound waves by the vibrating vocal cords, and the interaction of those two phenomena. A numerical simulation based on this model using the compressible Navier-Stokes equations has been accomplished. Results using a simplified two-dimensional geometry with a moving constriction representing the vocal cords are presented. They include the sound waves and the flow generated by the moving constriction. These are compared with theoretical values
