Obstructive sleep apnea is defined as the intermittent cessation of breathing during sleep, caused by airway obstruction. To study this phenomenon, a physical model of the airflow inside a constriction is described and associated to experimental data from an in-vitro set-up. This talk introduces a numerical model of the fluid-walls interaction in the pharynx and then compares simulations with experimental data.
