Experiments and Simulations of Exploding Aluminum Wires: Validation of ALEGRA-MHD

Abstract

The dynamics of a metallic, exploding wire (EW) contains rich and interesting physics. A large amount of study through the 1960s has been compiled in the four-volume workshops on the subject (1 4). Chace (5) provides an interesting EW history dating back as far as 1773 to Nairne as well as identifying applications such as detonating explosives (referred to as bridge wires) and photographic light sources, for example. One area that has been the subject of much research is the expansion rate of EW and its relationship to the rate of energy deposition (6, 7). For example, Sinars et al. (8) shows that for a variety of wire materials, the (wire core) expansion rates are related to energy deposition prior to plasma formation around the wire.
