Jet penetration of inerts and explosives. [2DE computer code]
The two-dimensional Eulerian hydrodynamic code 2DE, with the shock initiation of heterogeneous explosive burn model called Forest Fire, is used to model numerically the interaction of jets of steel or tantalum with steel, water, and explosive targets. The calculated jet velocity relative to the penetration velocity into inert targets is a function of the square root of the target density divided by the jet density. The calculated penetration into explosives, initiated by a low-velocity jet, are significantly less than for inerts of the same density. The detonation products near the jet tip have a higher pressure than that of nonreactive explosives, and thus slow the jet penetration. At high jet velocities, the calculated penetration velocities are similar for reactive and inert targets.
