Implosion of plasma liners in the presence of an axial magnetic field

Based on a radiative magnetohydrodynamic model, a numerical investigation is made of the implosion of single- and two-stage plasma liners with an initial axial magnetic field. The radiative magnetohydrodynamic model includes the equations of two-temperature hydrodynamics taking into account the electron and ion thermal conductivity, the electromagnetic field equations, and the equations of radiative transfer in a nonequilibrium medium. It is shown that in the case of a single-stage liner the implosion takes place in a subsonic regime, while the dynamics of a two-stage liner is determined by that of the propagation of shock waves of various intensities through the inner stage.
