    摘要: An hourglass-shaped cavitation chamber is provided. The chamber is comprised of two large cylindrical 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 as well as couple the chamber to a degassing and/or circulatory system can be attached to one, or both, ends of the chamber. When used, preferably the conduit or conduits are attached off-axis.

    摘要: A method of fabricating a spherical cavitation chamber is provided. Depending upon the chamber's composition and wall thickness, chambers fabricated with the disclosed techniques can be used with either low or high pressure systems. During chamber fabrication, initially two spherical half portions are fabricated and then the two half portions are joined together to form the desired cavitation chamber. During the fabrication of each chamber half, the interior spherical surface is completed first and then the outer spherical surface. Prior to joining the two spherical cavitation chamber halves, the surfaces to be mated are finished, preferably to a surface flatness of at least ±0.01 inches. Electron beam welding is used to join the chamber halves together. Preferably the electron beam welding operation is performed under vacuum conditions. During electron beam welding, the two chamber halves are aligned and held together while the electron beam forms a weld along the chamber seam.

    摘要: A method for initiating cavitation within the fluid within a cavitation chamber is provided. In the cavitation preparatory steps, a hydraulically actuated piston is partially withdrawn and then the cavitation chamber is isolated. Once the chamber is isolated, the hydraulic piston is further withdrawn in order to form the desired cavities and then extended to implode the cavities. At least one impeller, located within the cavitation chamber, is rotated in order to stabilize the cavities.

    摘要: A method for initiating cavitation within the fluid within a cavitation chamber is provided. In the cavitation preparatory steps, a hydraulically actuated piston is fully retracted and then the cavitation chamber is isolated. The hydraulic piston is then fully extended after which the chamber is partially opened until a predetermined cavitation piston position is obtained. After the chamber is once again isolated, cavities are formed and imploded by retracting and then extending the cavitation piston. At least one impeller, located within the cavitation chamber, is rotated in order to stabilize the cavities.

    摘要: An acoustic driver assembly for use with a spherical cavitation chamber is provided. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass, coupled together with a centrally located threaded means (e.g., all thread, bolt, etc.). The driver assembly is either attached to the exterior surface of the spherical cavitation chamber with the same threaded means, a different threaded means, or a more permanent coupling means such as brazing, diffusion bonding or epoxy. In at least one embodiment, the transducer is comprised of a pair of piezo-electric transducers, preferably with the adjacent surfaces of the piezo-electric transducers having the same polarity. The surface of the head mass that is adjacent to the external surface of the chamber is non-flat and has a spherical curvature less than the spherical curvature of the external surface of the chamber, thus providing a ring of contact between the acoustic driver and the cavitation chamber. In at least one embodiment, a void filling material is interposed between one or more pairs of adjacent surfaces of the driver assembly and/or the driver assembly and the exterior surface of the cavitation chamber.

    摘要: A method and apparatus for forming a temperature difference between two regions within a cavitation chamber is provided. The cavitation chamber is partially filled with cavitation fluid, thereby forming a cavitation fluid free surface which divides the chamber into a first region located above the cavitation fluid free surface and a second region located below the cavitation fluid free surface. The region above the cavitation fluid free surface is heated in order to form the desired temperature difference, heat being provided by a resistive heater or other means. In addition to heating the region above the cavitation fluid free surface, the region below the cavitation fluid free surface can be cooled, for example utilizing a refrigerated container, refrigeration coils, a thermoelectric cooler, or other means. A temperature monitor can be thermally coupled to the first region, the second region, or both.

    摘要: A cavitation system and method of use for loading the cavitation medium with a source gas, e.g., a reactant, prior to cavitation is provided. The cavitation system includes a cavitation chamber with suitable cavitation drivers and a pressurized gas source coupled to the chamber. A valve interposed between the source gas and the cavitation chamber controls the reactant loading process. In another aspect, a vacuum system is coupled to the cavitation system for use during degassing. The vacuum system may include a cold trap. Preferably multiple valves are used to couple/de-couple the vacuum system and the gas source to the cavitation system when required, for example as a means of protecting associated pressure gauges. In another aspect, the cavitation chamber and the cavitation medium fill reservoir as well as any coupling conduits in which the cavitation fluid is expected to flow are heated to a temperature greater than the melting temperature of the intended cavitation medium. Preferably the system components that must be heated are located within an oven. Alternately the desired temperature can be reached using localized heaters.
