Abstract : The liquid impact simulator is capable of shooting single jets of water of diameters varying from .020 inch to .100 inch at speeds up to 3000 feet per second. Minor adaptations of the apparatus could produce even higher velocity jets. These liquid jets are capable of pitting metal blocks, puncturing thin sheet metal, or cracking crystals. By varying the target position, the impulse loading rate can be altered. Photographs of jet behavior can be easily obtained. The speeds and masses of the water jets are comparable to those encountered in projectile flights through rain. However, jet diameters are smaller than those of raindrops with corresponding masses. Hence it is likely that longer and higher pressures are applied by the simulator jets. More knowledge of the mechanism of rain impact is necessary for a more accurate simulation. (Author)
