Abstract
A method of degassing cavitation fluid using a closed-loop cavitation fluid circulatory system is provided. The procedure is comprised of multiple stages. During the first stage, the cavitation fluid is continuously circulated through the cavitation chamber, reservoir and the circulatory system while the fluid within the chamber is cavitated. A vacuum system coupled to the fluid reservoir periodically degasses the fluid. During the second stage, pumping of the cavitation fluid through the chamber is discontinued. Gases released by the cavitation process are periodically pumped out of the chamber and periodically eliminated by the vacuum system. A third stage, although not required, can be used to further eliminate gases dissolved within the cavitation fluid. During the third stage cavities are formed within the cavitation fluid within the chamber using any of a variety of means such as neutron bombardment, laser vaporization or localized heating. Once formed, the cavities are cavitated, thereby releasing dissolved gases within the fluid which can then be removed using the circulatory system and the attached vacuum system.
