| Abstract: | A high pressure water jet cutting set similar to a jet pump which can better induce cavitation,is presented.Under nonsubmerged condition a series of tests for comparison between this cutting set and traditional single nozzle cutting set are conducted.Test results indicate that under the same operating conditions this cutting set has the advantages of lower energy consumption and bigger cutting depth over traditional single nozzle cutting set.Its optimum operating parameters are provided by test results. |
