Abstract :
Development of a two-dimensional magnetohydrodynamic (MHD) code to simulate internal motions in a railgun plasma armature is discussed. The authors use the equations of resistive MHD, with ohmic heating, and radiation heat transport. A flux corrected transport code is used to advance all quantities in time. The runs show the development of complex flow, subsequent shedding of secondary arcs, and a drop in the acceleration of the armature
