On the Initiation of High Explosives by Laser Radiation

“…When the explosive is heated, the internal temperature T is described by the heat conduction equation with a source term produced by the chemical reactions [1][2][3][4][5]: (1.1)…”

“…The initiation of HE surrounded by walls with fixed temperature T is a wellknown problem [1][2][3]. Below some critical temperature T c , the volume heat production is compensated by the thermal flux through the walls.…”

“…When the temperature becomes sufficiently high, thermal transport is unable to compensate for the energy production by chemical reactions, and a thermal explosion takes place. The critical temperature can be found as a maximal boundary temperature for which a stationary solution exists [1][2][3]. It is given by the solution of the equation…”

Flow of a two-fluid plasma carrying a pulsed current in a steady-state magnetic field

“…Magnetohydrodynamics Two-fluid magnetohydrodynamics is based on two equations, which separately describe the motions of the electron and ion plasma components and are only related by the friction force R ie between the components (see, e.g., [9][10][11][12]…”

“…Here, we introduce the dimensionless parameter (9) which is called the Hall parameter [13] and characterizes the degree of magnetization of the electron component of plasma. Indeed, when substituting σ 0 = Ne 2 τ e /m into Eq.…”
