  • The characteristics of underwater explosions, especially the distributions and the time histories of shock wave overpressures, which are generated by the underwater explosions of cased cylindrical charges initiated in one-end-point, are numerically simulated by using a two-dimensional multi-fluid hydrodynamic fortran code named MFIC. The cylindrical charges studied here are of four different explosives, including TNT, RS-211, T/ (35/65) and ROT901. For each explosive four TNT equivalents, 1 kg, 3 kg, 5 kg, and 8 kg, are considered. Each cylindrical charge has a length to diameter of L/D=1.5 and with a 3 mm thick Fe case or Al case. The spacial distributions of peak overpressure of underwater shock wave and overpressure time histories are obtained. Some overpressure time histories of different points and of different explosives for both Al case and Fe case are presented. The results of Fe case are compared with those of Al case.
