Correlation of Data on Jet Cutting by Water Jets Using Dimensionless Parameters.

摘要

Experimental data on the depth of slots cut in rocks,metals and other materials by traversing continuous liquid jets were correlated by an equation of the form: h/d =B ( P sub o/sigma sub c)-0.2) (V sub T/V sub 0) (exp-m),where: B= a constant for each material; h/d =slot depth in nozzle diameters; P sub 0 =jet pressure;sigma sub c =material compressive strength; V sub t =traverse velocity; V sub 0 =jet velocity; m = a constant in the range 0.5to 1.0. A discussion is given of the effects of nozzle standoff distance,material density and permeability and other parameters.
