... of the waterjet impinging upon the workpiece, rather than the net energy. The net energy transferred to the workpiece is a function of four key process parameters, namely, (i) orifice diameter, (ii) orifice geometry, (iii) supply pressure, and (iv) traverse rate. The energy density also incorporates jet spreading...

...Paul Feenstra; David S. Weaver; Zia Abdullah A wind tunnel study was carried out to investigate the fluidelastic stability of a model heat exchanger tube array subjected to a uniform cross-flow of air and a concentrated jet flow of air directed down a tube lane. The latter experiments were intended...

... must be developed and optimized for working at these high pressures. In previous work 2 , very small jets were used and were shown to achieve a great enhancement in power efficiency. The cutting of thin (1.6-mm) aluminum using a 0.025-mm-dia orifice resulted in significant improvements in cutting...

.... The plastic deformation in waterjet-peened test specimens caused fatigue cracks to initiate in the interior of test specimens. The degree of fatigue life improvement by waterjet peening found to be dependent on peening conditions, i.e., jet pressure, standoff distance, nozzle type, jet velocity, and peening...
