Abstract:
An hourglass-shaped cavitation chamber (100, 200) comprised of two large cylindrical regions (101, 103) or two large spherical regions (201, 203) separated by a smaller cylindrical region (105, 205) is provided. A ring-shaped acoustic driver (301) is coupled to one or both ends of the cavitation chamber. Alternately an acoustic driver assembly (701) is coupled to one or both ends of the cavitation chamber. Alternately an acoustic driver assembly (2601) is incorporated within the chamber wall at one or both ends of the cavitation chamber. Coupling conduits (313, 323, 501) which can be used to fill/drain the chamber as well as couple the chamber to a degassing and/or circulatory system can be attached to one, or both, ends of the chamber.
Abstract:
An acoustic driver assembly for use with any of a variety of cavitation chamber configurations, including spherical, cylindrical and chambers that include at least one flat coupling surface, is provided. The acoustic driver assembly includes a transducer assembly, a head mass and a tail mass. The end surface of the head mass is shaped to achieve the desired region of contact between the driver assembly and the cavitation chamber. The end surface can be shaped to define a ring of contact, a centrally located contact region, or spherically shaped with a curvature that matches the curvature of the spherical cavitation chamber to which it is attached. A threaded means is used to assemble the driver. The driver assembly can be attached to the cavitation chamber with the same threaded means, a different threaded means, an epoxy bond joint, a braze joint, a weld joint, a diffusion bond joint, or by other means. The head mass can be comprised of a pair of head mass portions coupled together with an all-thread.
Abstract:
An acoustic driver assembly for use with any of a variety of cavitation chamber configurations, including spherical, cylindrical and chambers that include at least one flat coupling surface, is provided. The acoustic driver assembly includes a transducer assembly (700) had mass (705) and eight mass (207). The end surface of the head mass is shaped to achieve the desired region of contact between the driver assembly and the cavitation chamber. The end or surface can be shaped to define a ring of contact, a centrally located contact region, or spherically shaped with a curvature that matches the curvatureof the spherical capitation chamber to which it is attached.
