Shockwaves in Fresh Water Generated by the Detonation of Pentolite Spheres
Abstract
Shock velocities as a function of distance were determined by differentiating distance-time paths of the shock waves. The distance-time information was obtained from high-speed photographs of the shocks obtained by a shadow-graphing technique. In addition, peak pressure and pulse time histories were recorded using lithium niobate gages. Pentolite spheres of three different initial radius (RO) were used in the gage experiments. The shock velocities were obtained for relative distances of R/RO ranging from 1.2 to 4.0 while the pressure date were obtained for R/RO ranging from 4.4 to 12.3. Scalability of peak pressure and pulse half-widths times as a function of R/RO was successfully demonstrated. An analytical form was found that fits the peak pressure data from R/RO of 1 to 12.
