The design of acoustic resonant chambers by numerical simulation

The pressure and velocity fields within a resonant chamber are calculated with the finite element, linear fluid/structure interaction code, ATILA(TM). Our ultimate objective is to create a standing wave of pressure strong enough to produce cavitation at the bulk of the fluid. Most researchers design these chambers by an expensive and time consuming process of trail and error involving the construction of many prototypes. We show that our numerical simulations agree closely with experiments and therefore computer assisted design is possible.
