Cavitation chamber degassing system
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.
