Abstract

Abstract

The local ohmic heating dominated dynamic ablation of Z-pinch wire-array is investigated numerically in 2D geometry using FOI-PERFECT code. Mass ablation rate, precursor current and ablation time are analyzed quantitatively to investigate the effects of initial wire plasma diameter and wire number on the ablation of wire-array. Numerical results demonstrate that the increase of wire number and/or initial wire plasma diameter leads to the increase of mass ablation rate and the decrease of precursor current and ablation time. This conclusion agrees with the simulation works of other authors.
