Dynamic Characteristics of Waterjets Generated from Oscillating Systems

Abstract

In the last decades, there was a considerable increase in the use of pressurized waterjets as a novel means of cutting and cleaning surfaces in a wide variety of industrial applications. The fluctuating dynamic force exerted by a waterjet on impact was analyzed both in the time domain and the frequency domain. The effects of pump characteristics, hose and high pressure tubing, support constraints, nozzle geometry, jet velocity or pressure and stand off distance were ascertained. A magnetic shaker was employed to excite the end of the nozzle, both perpendicular and parallel to the ejecting direction of the jet. Correlations between the imposed excitation and the impact force from the waterjet were delineated.
