| Summary: | The feasibility of using a focused shock wave in a water-filled elliptical cavity to produce repetitive, high-speed water jets with enough energy to eject small particles in a material sorting system was studied. A weak shock wave was produced by means of an electrical discharge at the one focus of the ellipse. The wave was concentrated under a nozzle located above the second focus where the high pressure caused a slug of water to be ejected out of the nozzle at high velocity. Electrical and mechanical factors influencing the jet performance were analyzed together with the results of a finite difference simulation of shock wave propagation in the elliptical cavity. High-speed photography was used to reveal the flight of the ejected water slugs. |
