Modelling the human pharyngeal airway: validation of numerical simulations using in vitro experiments
Franz Chouly, Annemie Van Hirtum, Pierre-Yves Lagrée +2
In the presented study, a numerical model which predicts the flow-induced collapse within the pharyngeal airway is validated using in vitro measurements. Theoretical simplification…
Experimental Validation of Simplified Free Jet Turbulence Models Applied to the Vocal Tract
Xavier Grandchamp, Annemie Van Hirtum, Xavier Pelorson
Sound production due to turbulence is widely shown to be an important phenomenon involved in a.o. fricatives, singing, whispering and speech pathologies. In spite of its relevance…
A preliminary study of asymmetric vocal fold vibrations: modeling and "in-vitro" validation
Nicolas Ruty, Annemie Van Hirtum, Xavier Pelorson +2
This paper deals with some of aspects of the influence of asymmetry on vocal folds vibrations. A theoretical model of vocal fold asymmetry is presented. The influence of asymmetry…
A mechanical experimental setup to simulate vocal folds vibrations. Preliminary results
Nicolas Ruty, Annemie Van Hirtum, Xavier Pelorson +2
This paper contributes to the understanding of vocal folds oscillation during phonation. In order to test theoretical models of phonation, a new experimental set-up using a deforma…
Reproduction of hypopnea phenomenon using a physical and numerical model
Franz Chouly, Annemie Van Hirtum, Pierre-Yves Lagrée +2
Obstructive sleep apnea syndrome is now considered as a major health care topic. An in-vitro setup which reproduces and simplifies upper airway geometry has been the basis to study…
Physical modelling of the airflow-walls interactions to understand the sleep apnea syndrome
Yohan Payan, Xavier Pelorson, Pascal Perrier
Sleep Apnea Syndrome (SAS) is defined as a partial or total closure of the patient upper airways during sleep. The term "collapsus" (or collapse) is used to describe this closure.…
