The external velocity augmentation concept was demonstrated by striking a flat plate with a flat-faced slug of water to create a jet with a velocity eight times that of the slug. A generator capable of providing flat-faced slugs at a velocity of 1000 ft/sec was designed, built, instrumented, and tested. Experimental studies were made of interface devices capable of maintaining a 1/2 inch vertical face of water at the end of a horizontal channel. Pressure pulse characteristics at various points in the generator and slug velocity and form were analyzed to optimize slug generation techniques. Results showed superiority of flat impingement plate concept to the two slug concept as a method of achieving external velocity augmentation. (Author)
