Peculiarities Of Planar Shockwave Interaction With Air-Water Interface And Solid Target

We present the results of experiments performed at the European Synchrotron Radiation Facility where, using phase-contrast imaging, the explosion of a planar wire array was studied. In experiments, a pulse generator (880 nF, 30 kV, 30 kA, current rise time of ~1 μs ) was used for the critically damped explosion of a planar copper wire array submerged underwater. Following the explosion, a strong shockwave, having planar symmetry, interacted with either an air-water interface or an aluminum target located 4-5 mm above the wire array.
