CORRELATION OF DATA ON LIQUID JET CUTTING OF ROCKS AND OTHER MATERIALS

A method has been developed using dimensionless parameters to correlate data on the depth of slots cut in materials by traversing high-pressure continuous liquid jets. It is a generalization of an equation presented by Nikonov and Goldin for application to rocks and coal. In addition to the effect of jet pressure and traverse velocity, it permits taking account of the jet and material densities, standoff distance from the nozzle to the material surface, and the nozzle discharge coefficient. The effect on jet coherence of nozzle Reynolds number and the effect of turbulence and vorticity produced by the feed system at the inlet of experimental nozzles have not been included, although they are believed to be significant factors.
