The effect of radial dynamics on the stability of diffuse profile Z pinches

D. Zdravkovic, M. Coppins, A. R. Bell

Open publisher page 4 citations

Abstract

The effect of radial dynamics on the ideal magnetohydrodynamic (MHD) linear m=0 instability in diffuse profile Z pinches is investigated with a two-dimensional (2D) MHD code. The radial dynamics impose a periodic behavior within which three distinct phases of instability development can be distinguished. The comparison with the Rayleigh–Taylor instability is presented. The behavior is best characterized as MHD instability enhanced by the radial dynamics.
