Water Jet Nozzle Performance Tests

Abstract

Five nozzles were tested to observe their ability to cut Berea sandstone in stationary cutting tests, to produce coherent jet structure for large distances from the nozzle, and to cut limestone in rotating cutting tests. Four nozzles were 8 deg dual orifice diverging nozzles which were all similar in their internal configuration except for the quality of the surface finish. The differences in the surface finish resulted from manufacturing one nozzle from brass on a conventional milling machine, pressing carbide around a pair of mandrels and sintering, then polishing one of a pair of the carbide nozzles, and electroforming from nickel a dual orifice diverging nozzle. The nozzles with the best surface finish were the electroformed nickel nozzles, and they performed significantly better than the other nozzles.
