Sliding interface processing in simulation on magnetically driving high speed flyer

The flyer plates and the electrodes interact in the emission experiment of high-speed magnetically accelerated flyer plates. The area surrounding the flyer plates and electrodes should be considered in numerical simulation. Hence, a two-dimensional multimedia code is developed on the basis of MDSC2 and numerical simulation of the magnetically accelerated flyer plates is conducted. The results show that the solid density is constantly kept in the free surface of the flyer plates; the speed history of the free surface matches the experimental records by velocity interferometry system for any reflector (VISAR). The middle of the flyer plates keeps a good degree of planarity in the loading procedure of electric currents while the tailing mass at the two ends of the flyer plates is unstable because of the distinguished magnetic strengths between the ends and the middle of the flyer plates.
