Abstract
An apparatus for cavitation and sonoluminescence is provided. In some embodiments the apparatus provides high-intensity shock waves that modify the properties of the liquid medium in the resonator and thereby alter the optical and electrical properties of the liquid. Methods for studying the acoustical and optical characteristics of the liquid and the sound fields in such scenarios are enabled and thereby testing and analysis of the same are made possible.
Claims23
A system for achieving cavitation within a liquid medium comprising:
- a resonator having a shell body substantially enclosing the liquid medium and defining an inner volume within which the liquid medium is confined;
- a driving element coupled to said resonator for imparting energy to the resonator for causing cavitation in at least one region of the fluid medium within said resonator;
- a fluid pressure control apparatus to control a static pressure of the fluid medium within said resonator;
- and
- an aperture within said shell body through which electromagnetic radiation may pass.

A method for determining an optical characteristic of a fluid medium comprising:
- placing said fluid medium in a substantially enclosed resonator volume;
- raising a static pressure of said fluid medium within said resonator to a given static pressure range;
- applying an acoustical driving energy to said resonator so as to cause a sonoluminescence event in at least one region of said fluid medium within said resonator and so as to emit light from said region as a result of said sonoluminescence event;
- and
- determining a phase of said fluid medium where said phase deminishes a transmission characteristic of at least a range of wavelengths of said light emitted from said sonoluminescence event.
