Název v původním jazyce

On mathematical modelling and numerical simulation of human phonation process

Popis výsledku v původním jazyce

Mathematical modeling in the field of biomechanics of human voice is a challenging task, namely due to the fact that this phenomena is a complex process involving, e.g., fluid-structure interactions and aeroacoustics. The fundamental sound is created by vibrations of vocal folds in the trachea induced by the airflow coming from the human lungs. These vibrations are caused by the aeroelastic instability of the fluid-structure system, thus solution of the FSI problem is required. The created primary sound is further modulated by the geometry of the vocal tract corresponding to a pronounced vowel. Problems of fluid-structure interaction (FSI) are involved in various technical as well as scientific applications. Let us mention aeroelasticity important in aerospace applications or biomechanics of voice, see e.g. [2, 4]. Although the classical methods based on linearized aerodynamics are standard tools due to their efficiency, during the last decades also numerical simulations have become a viable alternative tool to analyze such problems.
