Adaptation of Jet Accumulation Techniques for Enhanced Rock Cutting
The velocity of a waterjet can be increased when the jet impacts a target material or another waterjet. A theory describing such augmentation in terms of velocity, mass, and energy change is considered. The phenomenon is sensitive to jet structure and the jet velocity profile. Jet velocity profiles do not remain constant over great distances from the nozzle, and ultimately disrupt into droplets. Within the droplet the profile is more regular and the velocity constant. The theory is extended to cover the case of droplet collisions, and experiment evidence of jet augmentation and its effets is presented. (A)
