A cavitation system in which a source gas, e.g., a reactant, is loaded into the cavitation medium prior to cavitation is provided. The cavitation system includes a cavitation chamber with suitable cavitation drivers and a cavitation medium reservoir, the chamber and reservoir being flexibly coupled together via a pair of conduits. The conduits can be fabricated from a plastic or, as is preferred for higher temperature liquids, a metal. Typically metal conduits are formed into a coil, thus providing the desired flexibility. Flexibility is required in order to allow the relative positions of the cavitation chamber and the cavitation medium reservoir to be varied. The system is configured such that the cavitation fluid will flow out of the cavitation chamber, through the lower coupling conduit and into the cavitation medium reservoir when the chamber is positioned higher than the reservoir, and flow out of the cavitation medium reservoir, through the lower coupling conduit and into the cavitation chamber when the reservoir is positioned higher than the chamber. As a consequence of this configuration, cavitation fluid can be readily exchanged between the cavitation chamber and the cavitation medium reservoir, thereby aiding the degassing process as well as providing a means of replenishing reactant-depleted cavitation medium.

Method for circulating a cavitation medium

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 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.

A system for achieving bubble stability within a cavitation chamber is provided. The system includes an impeller assembly, the impeller assembly having at least one impeller blade located within the cavitation chamber. The impeller assembly is magnetically coupled to an external drive system which is used to rotate the impeller, thereby causing bubbles within the cavitation chamber to move toward the impeller's axis of rotation. As a consequence, the bubbles become more stable. Preferably the axis of rotation of the impeller is positioned in a substantially horizontal plane, thus allowing the rotating impeller to counteract the tendency of the bubbles to drift upward and to accumulate on the upper, inner surfaces of the cavitation chamber. The impeller can be rotated continuously throughout the cavitation process or stopped prior to, or during, bubble cavitation. In the latter scenario, the impeller can be stopped, and if desired locked, at a specific rotational position, thus minimizing possible interference between the impeller and the source of the cavitation energy. The impeller can be shaped to correspond to the inner surface of the cavitation chamber, for example spherically or cylindrically, and can utilize multiple impeller blades.

A method and apparatus for regulating the temperature of the cavitation medium for a cavitation chamber is provided. The cavitation medium is pumped through the cavitation chamber through a pair of chamber inlets and an external conduit connecting the two inlets. An external heat exchanger is used to regulate the cavitation medium temperature, the heat exchanger being either directly or indirectly coupled to the conduit. The cavitation medium can be circulated through the heat exchanger during chamber operation or, once the desired cavitation medium temperature is achieved, operation of the circulation system can be suspended. The heat exchanger can be used to lower the temperature of the cavitation medium to a temperature less than the ambient temperature; to withdraw excess heat from the cavitation medium; or to heat the cavitation medium to the desired operating temperature. The heat exchanger can utilize heated heat exchange fluid, cooled heat exchange fluid, thermoelectric coolers, heat sinks, refrigeration systems or heaters. The cavitation medium circulation system can be configured to include a filter and/or a degassing chamber.

Apparatus for replenishing a source gas in a cavitation medium

A system and method for degassing a cavitation fluid is provided. The cavitation system of the invention includes a cavitation chamber with one or more cavitation drivers and a degassing system coupled to the chamber. One or more heaters, such as resistive heaters, are coupled to an external surface of the cavitation chamber such that heat from the heaters is transmitted through the wall of the cavitation chamber and into localized regions of the cavitation fluid contained within the cavitation chamber. The heater or heaters increase the temperature of the localized regions of the cavitation fluid to a temperature above the boiling temperature of the cavitation fluid, thereby creating vapor bubbles which capture gas trapped within the cavitation fluid through a rectified diffusion process. A cavitation fluid cooler can be used to insure that the average temperature of the cavitation fluid is below that of the boiling temperature.

Cavitation chamber degassing system

A system for achieving bubble stability within a cavitation chamber is provided. The system includes an impeller assembly, the impeller assembly having at least one impeller located within the cavitation chamber. A motor, coupled to the impeller by a drive shaft, rotates the impeller thereby causing bubbles within the cavitation chamber to move toward the impeller's axis of rotation. As a consequence, the bubbles become more stable. Preferably the axis of rotation of the impeller is positioned in a substantially horizontal plane, thus allowing the rotating impeller to counteract the tendency of the bubbles to drift upward and to accumulate on the upper, inner surfaces of the cavitation chamber. The impeller can be rotated continuously throughout the cavitation process or stopped prior to cavitating the bubbles within the cavitation chamber. In the latter scenario, the impeller can be stopped, and if desired locked, at a specific rotational position, thus minimizing possible interference between the impeller and the source of the cavitation energy. The impeller can be shaped to correspond to the inner surface of the cavitation chamber, for example spherically or cylindrically, and can utilize multiple impeller blades.

Fluid rotation system for a cavitation chamber

A method of fabricating a spherical cavitation. 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.
