Abstract

The donor and the acceptor charges are arranged into the water with the interval. The donor charge has a cylindrical geometry with 30 mm diameter and 50mm long. The acceptor has a disk form with 100mm diameter and 10 or 5 mm thickness. Composition B is used for both of the donor and acceptor charges. The propagation processes of underwater shock waves from the top end of acceptor charge along the axis of charges are taken by the image converter camera under the intervals of 10, 15, 20 and 25mm. In the case of 10 mm thick acceptor charge, the velocities of the underwater shock wave are the almost the same up to the interval of 20 mm. However, in the case of 25 mm the underwater shock wave has remarkable low velocity compared to the other cases. In the case of 20 mm interval, the velocity of the underwater shock wave in the case of the 5mm thick acceptor is slower than that of 10 mm. Furthermore, the numerical simulations are conducted. The reaction rate law of the high explosive is a phenomenological mode l that is proposed by Lee and Tarver. The results of the optical measurement and numerical simulation demonstrate a good agreement.
