Detonation equation of state at LLNL, 1995. Revision 3

Abstract: JWL's and 1-D Look-up tables are shown to work for "one-track'' experiments like cylinder tests, plate shots and the expanding sphere. They fail for "many-track" experiments like the compressed sphere. As long as the one-track experiment has dimensions larger than the explosive's reaction zone and the explosive is near-ideal, a general JWL with R1= 4.5 and R2 = 1.5 can be constructed, with both o and Eo being calculated from thermochemical codes. These general JWL's allow comparison between various explosives … Show more

“…After the sonic point, the system transitions to an adiabatic expansion. Note that the Von Neumann spike is higher in Figure 10 than is commonly supposed (C. Souers, private communication 14 ). This is due to the unreacted HMX equation of state.…”

“…Moreover, the equation of state can be easily recalibrated in order to match the experimental results. The constants have often been determined with the cylinder test [4] where the lowest pressure reached is about 4 GPa. In this paper, parameters of the JWL equation of state are calibrated with the thermochemical code SIAME 1.0 (SImulation of Aerothermochemical of Mechanics of Explosives).…”

“…There are two ways to determine the JWL parameters of equation of state: (1) by use of a thermo-chemical equilibrium code, and (2) using some of the experimental tests. The former method implies the use of a mentioned semi-empirical computer program that has a JWL fitting procedure built in, e. g. [6,7], and will not be considered here. The latter approach, which is based on detonation products expansion physics, will be further investigated.…”

“…The most common source of experimental data to obtain explosive performance parameters is the cylinder test [7][8][9][10]. A copper tube is filled with the explosive of interest and the planar detonation wave (normal to the cylinder axis) is generated as shown in fig.…”
