  • Method and apparatus for generating large velocity, high pressure, and high temperature conditions
    Patent number: 5968323
    Abstract: A method of concentrating energy to produce large velocity, high pressure and/or high temperature conditions, including the steps of forming a resonant cavity inside a container; filling the resonant cavity with a liquid having a compressibility that is smaller than that of water at room temperature; coupling energy into the resonant cavity at a frequency which drives the resonant cavity at or near a resonant mode thereby creating one or more velocity nodes in the resonant cavity; and capturing a quantity of material or mixture of material in the resonant cavity at one of the velocity nodes.
