Abstract
The wire explosion technique generates plane shock wave by exploding parallel metal wire rows, using a shock large current. In this study, we investigated underwater shock wave generated from four kinds of metal wires (copper, alumel, SUS304, nichrome) using the shadowgraph method and a high-speed camera (IMACON 468 of HADLAND PHOTONICS, interframe times 10ns to 1ms in 10ns steps independently variable number of channels framing:4 streak:1). The explosion power of a metal wire showed a good relation to its rate of electric resistance. It seems that a strong shock wave is obtained, if the bold wire using a mass condenser bank is exploded.
