Numerical simulation of implosion of solid liner driven by disk explosive magnetic generator

Based on the simplified model of electrically exploded opening switch(EEOS) and the zero-dimension model of solid liner, the code D-liner, which was designed to simulate implosion of solid liner driven by disk explosive magnetic generator(DEMG) with EEOS, was compiled with Matlab. To optimize the parameters of solid liner and analyze the variation of parameters, such as the voltage of EEOS, radius and velocity of liner and the effect of EEOS on DEMG current, the system with DEMG, EEOS and solid liner was simulated. The simulation results show that when the initial current is 5.9 MA, the 400 mm ten-element DEMG with EEOS, whose length is 72 cm and thickness is 120 m, can output 31 MA current on 50 g cylindrical aluminum liner with a characteristic rise time of 1.6 s, that the EEOS can transfer high voltage (230 kV) to the liner and that the 50 g cylindrical aluminum liner can be driven to 13.7 km/s.
