Abstract

Abstract

To determine the range and the influence factor of structure coefficient and, the relation between structure coefficient and influence factor, numerical simulations and analysis of magnetically driven flyer plate experiments on PTS facility are carried out. The numerical simulations show that the magneto-hydrodynamic code can correctly simulate each magnetically driven flyer plate experiment on PTS facility. The structure coefficient of magnetically driven two-sided flyer plate experiment is about 0.7−0.8 and the structure coefficient of one-sided experiment is about 0.80−0.85. The structure coefficient is independent of the measured experimental current, and only determined by the initial structure of experiment load. The structure coefficient is related to the initial widths of anode and cathode, the initial gap between anode and cathode, and the sum of depths of flyer plates on anode and cathode. When the initial widths of anode and cathode and the initial gap between anode and cathode are fixed, the greater sum depths of flyer plates on anode and cathode, the greater the structure coefficient of magnetically driven flyer plate experiment.
