摘要：
MACH2 is a general purpose MHD code that has been used to simulate the evolution of an explosively formed fuse consisting of a thin cylindrical aluminum shell that is driven into a Teflon die by an explosion. The simulations included the initiation and propagation of the explosive detonation wave and tracked the extrusion of the fuse into the Teflon die. The code predicted three orders of magnitude due to lengthening and thinning of the fuse material and the rise of temperature caused by the ohmic heating.
