Z箍缩丝阵烧蚀的简单模型数值模拟
Numerical modeling of Z-pinch wire array ablation with a simple model
摘要
Abstract
A good understanding of Z-pinch wire array ablation is of critical importance to the study of the dynamics of the wire array Z-pinch.To model the ablation process,a two-dimensional (2D) magnetohydrodynamics (MHD) program called FOI has been developed.The ablation is approximated in an adiabatic single-fluid single-phase MHD framework.Eulerian computation is adopted with a monotonic advection scheme.The numerical results obtained from FOI successfully qualitatively demonstrate the primary aspects of the ablation process,such as the core-corona structure,radial plasma streams,the formation of an on-axis precursor plasma column,longevity of the stationary wire cores and the extended ablation phase,though some discrepancies are observed.关键词
