Numerical Simulation of Magnetically Driven Sample Experiment

The magnetically driven sample experiments which were carried out in an intense pulsed power device were simulated and analyzed by two-dimensional magnetically driven simulation code (MDSC2), and the structure coefficient of magnetically driven sample experiments was studied and analyzed. The numerical results show that MDSC2 can correctly simulate experiments of magnetically driven samples such as tin and magnesium-aluminum alloy. The simulated sample/window interface velocity (or flyer plate/window interface velocity) is basically consistent with the experimental measured one. The structure coefficients of magnetically driven samples are usually different when the magnetically driven sample experiments are different. The structure coefficient of magnetically driven sample experiment is related to the initial conditions such as the sample material and the width of the electrode plate but not to the initial thickness of the sample material. Under the same initial conditions, such as the thickness of the flyer plate, the material of the flyer plate, the material of the sample, the initial gap between the cathode and the anode, the wider the electrode plate, the larger the structure coefficient of the magnetic drive sample experiment. MDSC2 can correctly simulate the magnetically driven sample experiments, which makes MDSC2 an important tool for the study of magnetically driven sample experiments.
