Numerical calculations the cuprum vapours liner dynamics

The dynamics of fast cuprum vapours z-pinch has been investigated. Two dimentional axisymmetrical problem was considered. We used the set of electronic magnetohydrodynamics (EMHD) equations. For the numerical solution the physical processes splitting was used. On the first step of the splitting the ideal MHD model with frozen in magnetic field was considered. For solving the ideal two-temperature MHD equations the implicit difference scheme was constructed. The scheme based on the calculus of variation. The calculation of liner dynamics depends on the Hall parameter was performed. The type of magnetic field evolution changes qualitatively when the value of the Hall parameter increases. The “tongues” of the magnetic field forms along the electrode.
