The High-Speed Photography of Liquid/Solid Impact

A study has been made using high-speed photographic methods of the phenomena occurring when a solid surface is struck by a small mass of liquid moving at very high speeds. An apparatus has been constructed for projecting small (1 mm diameter) cylinders of water at solid surfaces at velocities up to 1000 m/sec. The flow of the liquid mass and the break-up of the solid target on impact have been photographed using a Beckman & Whitley rotating mirror camera (Model 189) and also a 6-spark Cranz-Schardin system. Schlieren and photoelastic techniques have been used to determine the stress distribution within the target material during impact. — By using these methods it has been possible to show that most of the deformation of the target is due to compressible behavior within the colliding liquid mass. Failure due to the shearing action of liquid flowing over the surface of the target and to the reflection and interference of stress waves in the target itself is also considered.
