“…The core is surrounded by a plasma ''corona'' that contains only a small fraction of mass but carries almost all the current. This conclusion was made in the paper by Aranchuk et al (1986) specifically devoted to experimental studies of single-wire explosions [see also an earlier paper by Aranchuk, Bogolyubskii, and Tel'kovskaya (1985)]. They found that, in explosions of 20-m-diameter copper wires, only 2-7% of the total mass was carrying the current and radiating.…”

“…These schemes would give rise to very large energy release per pulse, in the range of 1 GJ (approximately equivalent to 250 kg of high explosives). Strong heating of a CH fiber plasma in the zone of a deliberately created constriction was observed by Aranchuk et al (1997). Numerical simulations by Lindemuth (1990) have shown spontaneous formation of hot spots as a result of the development of a sausage instability in cryogenic deuterium fibers.…”

“…For this, the rapid compression of thin-walled cylindrical shells (liners) is used. Experiments on the collapse of liners are conducted in several laboratories worldwide, including at the largest generators in Russia -Angara-5-1 [4] and S-300 [6,7,8], in Britain -the MAGPIE generator [5] and in the USA -the world's largest generator "Z" [9]. In recent decades, high energy density physics has been developing rapidly.…”

Numerical solution of problems of plasma dynamics with a neutral layer

Mathematical modeling on a computer is widely used in problems of magnetic hydrodynamics and dynamics of ionized gas (plasma). In these problems, in addition to the equations of mass, momentum, and energy balance that are common in continuum mechanics, it is necessary to solve Maxwell’s equations for the electromagnetic field. An urgent and interesting problem in the theory of ionized gas is the problem of changing the topology of the magnetic field in plasma during the processes of magnetic field lines reconnection. Such situations are characteristic of plasma processes in the Earth’s magnetosphere (natural processes and the ones resulting from active experiments in space) and in laboratory facilities for the creation of closed configurations. Because of the difficulties of diagnostics, mathematical numerical modeling is of great importance. The article presents twodimensional mathematical models of the processes of magnetic field lines reconnection occurring in plasma with finite conductivity in the vicinity of the neutral surface. Effective numerical algorithms are constructed for solving problems of plasma dynamics in the approximation of one-fluid magnetohydrodynamics. Calculations are conducted taking into account dissipative processes. The problem of transportation and interaction of closed plasma configurations in a single computational domain was solved.
