Brief description Matched experimental observation and finite-element simulation of flow-induced oscillations in uniform and tapered-stiffness collapsible tubes. Flexible tubes that can be flattened are widespread in the body and can act to limit flow-rate. Limitation is usually associated with spontaneous oscillation (repetitive opening and closing). There are many candidate explanations, but none has been shown to correspond with a given experiment. Through computer models and matched experiments on this coupled system (the fluid flow interacts with the tube shape), we seek to demonstrate for the first time that a given theory/computer model encompasses the physics controlling a given observed oscillation. The solution will find application in other flexible-structure design problems in engineering, and also potentially in medicine.
