NUCLEAR EXPLOSIONS IN A IONOSPHERE WITH FINITE ELECTRIC CONDUCTIVITY IN THE PRESENCE OF A UNIFORM MAGNETIC FIELD,

Abstract

In the following report the problem of a nuclear explosion in the ionosphere approximated by an expanding spherical bubble has been investigated. Based on the assumption of finite electric conductivity, there are two regions of interest, the plasma and the expanding bubble. Finite electric conductivity changes the system of equations from a purely hyperbolic to a mixed system. For this two-dimensional unsteady flow problem, the method of characteristics is far more difficult, since the characteristics are surfaces instead of curves. A numerical method involving a three-dimensional grid has been developed. (Author)
