Elaboration d'un prototype de distributeur auto-régulé

This study focuses on the interactions between a fl uid and a hyperelastic membrane whose function is t o regulate flow. The behaviour of the membrane under pr ssure stress was simulated using Abaqus. These results were used to model the flow (commercial CFD ) when the membrane is distorted and to determine i ts flow versus pressure law. These developments are ba s d on numerical finite element method and an iterative solution algorithm for coupling. The nume rical models are validated experimentally. This wor k contributes to the development of a prototype of re gulated emitter. Mots clefs : Interactions Fluide-Structure, Analyse axisymétriqu e, Déformation du maillage.
