THE DESIGN OF ACOUSTIC CHAMBERS FOR BUBBLE DYNAMICS RESEARCH

Краткое описание
The purpose of this article is to describe a methodology for designing high efficiency acoustic chambers. ATILATM, a finite element method (FEM) based code, was used to numerically solve the mathematical model detailed in this paper, which accounts for fluid/structure interaction, acoustic waves and the physics of piezoelectric materials. A high-Q (i.e., strongly resonant) acoustic chamber was built according to ATILATM simulations to study sonoluminescence and sonofusion. The as-built chamber was experimentally characterized by measuring the pressure profile and frequency response in the liquid using a traversing hydrophone. Excellent agreement was found between the code predictions and measurements demonstrating the validity of the mathematical model and the reliability of the ATILATM code.
