Abstract
The present invention provides for an assembly for creating a pressure pulse in a liquid-filled cavity within a fracturable material such as a boulder wherein the primary energy storage element is disposed in a tranducer at the boulder to improve the coupling of energy between the energy storage unit and the fluid in the boulder.
Claims20
An assembly for creating a pressure pulse in a liquid-filled cavity within a fracturable material, said assembly comprising:
- a transducer;
- an energy storage component disposed in said transducer;
- a cable connected to said storage component for delivery of electric current;
- and
- a plurality of electrodes for converting the electrical current into a plasma pressure source.
2 more elements
An assembly for creating pressure waves in a liquid to fracture material, said assembly comprising:
- a transducer;
- one or more pairs of electrodes disposed on said transducer, said electrodes defining a gap therebetween through which an electrical current passes to create pressure through expansion of liquid as it undergoes a phase change to gas or plasma.
