Magneto-Hydrodynamic Simulations of a Magnetic Flux Compression Generator Using ALE3D

Abstract

Magnetic flux compression is a proven technique for the generation of ultrahigh magnetic fields, large currents, and large energy densities. The intent is to supply a few mega-amperes of seed-current for a fast high current when large capacitor banks are not available. A magnetic flux device consists of coils surrounding a cylindrical armature where an explosive drives the armature radially and causes a drop in the inductance. In this report, the results of ALE3D magneto-hydrodynamic simulation of a magnetic flux compression generator designed by the US Army Research Laboratory are presented. The simulation results are compared with the experimental data from 3 experiments with identical generators but different seed-currents. The simulation results show good agreement.
