Abstract

Results of experimental research and numerical simulations related to two applications of the underwater electrical explosion (UEWE) of various symmetric wire arrays for the study of high energy density physics are presented. We explored how the rise-time of the generator affected energy deposition into underwater wire explosions, and the subsequent effects this had on shockwave generation and water flow. One application is the acceleration of flyer plates (targets) realized by strong shockwaves and subsequent Waterflow, generated by the UEWE of a planar wire array. In experiments, targets were accelerated to velocities of ≤1.3 km/s with energy efficiency transfer of ≤20% from the deposited energy. Another application is the generation of supersonic (∼3-4 km/s) water jets by the UEWE of cylindrical/conical wire arrays. Jet generation occurs due to extremely high pressure and density of water formed in the vicinity of the axis by imploding shockwave and cumulation effect of converging shockwave at the edge of the cylindrical/conical array.
