  • The techniques of magnetically driven quasi-isentropic compression and magnetically driven hyper-velocity flyer plates are new experimental method and tool, which are developed in the last decade and widely applied in the fields of shock dynamics and high energy density physics.The physical process of magnetically driven flyer plates was simulated by three-dimensional magneto-hydrodynamics software.The calculated free surface velocities agreed well with the experimental results.The magnetic diffusion velocity and effective thickness of flyer plate were obtained by results of temperature, density and magnetic field profiles.The simulation results show that the side edge deformation of flyer plate is mainly caused by the non-uniformity of Lorentz force associated with the inhomogeneous distribution of current along the width direction of the electrode panel.Thus, the edge deformation can be improved by optimizing the current distribution on the loading surface of electrode panel along the width direction.
