| Abstract: | The seminar will be devoted to experimental and numerical studies of the generation of strong converging shock waves which are produced by underwater electrical explosion of wire arrays using a high current pulse generator with microsecond timescale. First part of the seminar will be devoted to experimental and numerical investigation of converging shock waves generated by underwater electrical explosions of spherical wire arrays. The results show that high values of temperature and pressure can be obtained with relatively low energy deposition at the vicinity of implosion.The second part will be dedicated to numerical investigation of an explosion of a planar wire array with different boundary geometries which allow the convergence of the generated shock wave. The results show that with the same stored energy, higher values of temperature and pressure are obtained with a specific boundary. |
