Numerical simulations of four types of gap tests were performed to generate calibration curves and to produce distance-vs-time diagrams of these tests. These gap tests include test samples: in the first test, the acceptor is unconfined; in the second and third tests, the acceptor is confined in steel tubes; and in the fourth test, the entire assembly is submerged in a water bath. The gap test model is two-dimensional with cylindrical symmetry. To model the gap test, we used the reactive hydrodynamic code 2DE with the Forest Fire law that computes the burn rate of a high explosive. Calibration curves were generated for pressure and for particle velocity. Corresponding distance-vs-time diagrams were produced for the shock front, for the back surface of the gap material, and for the rarefaction wave. A comparison of the results from our simulations with experimental data shows good agreement. 12 refs., 22 figs.
