OSAS (Obstructive Sleep Apnea Syndrome) is a sleep related
breathing disorder caused by repetitive collapses of the pharyngeal walls during sleep. The objective of this project
is to supply experimental data to validate CFD simulations of
fluid-structure Interaction (FSI), used in the prognosis of surgeries for OSAS.
A testrig to investigate the FSI of flow over a rigid plate with an attached elastic plate was designed, built and tested. Velocity profiles (derived from pitot tube pressure measurements) normal to the elastic plate and behind the elastic plate were measured as air flows by, and the motion of the elastic plate was recorded with a highspeed camera. Furthermore the recordings were analyzed and the movement of the flexible plate was determined. The experiments were realized with pitot-tube measurements and high-speed camera recordings.
