Abstract
An hourglass-shaped cavitation chamber is provided. The chamber is comprised of two large spherical regions separated by a smaller cylindrical region. Coupling the regions are two transitional sections which are preferably smooth and curved. Although the chamber is preferably fabricated from a machinable material, such as a metal, it can also be fabricated from a fragile material, such as a glass. An acoustic driver assembly is incorporated within the chamber wall at one end of the cavitation chamber. The driver can be threadably coupled to the chamber or attached using an epoxy, diffusion bonding, brazing or welding. O-rings or other seals can be used to seal the driver to the chamber. The head surface of the driver assembly can be flush, recessed, or extended from the internal chamber surface. The head surface of the driver assembly can be flat or shaped. If desired, a second acoustic driver assembly can be incorporated within the chamber wall at the other end of the cavitation chamber. Preferably the driver or drivers are attached such that their central axis is coaxial with the central axis of the cavitation chamber. Coupling conduits which can be used to fill/drain the chamber…
