Abstract:

A model previously developed to investigate current and heat transport in solid-armature railguns is extended. The 2-dimensional model involves the numerical solution of coupled Maxwell and heat-transport equations in both the armature and rails of the railgun. The principal extensions include the development of a general transformation which maps an armature of fairly arbitrary shape into a rectangular computational region, and the inclusion of melting within the appropriate governing equations. Two specific applications of the theory are then discussed analysis of an armature under experimental study at the Army Research Laboratory and preliminary calculations concerning the entrainment of armature material on the surfaces of the rails.
