Numerical model of the gap test. [PBX-9404; TATB, VTQ2, and Composition B]
The Los Alamos Scientific Laboratory (LASL) standard gap test and the Naval Ordnance Laboratory (NOL) large-scale gap test are modeled numerically using the LASL reactive hydrodynamic code 2DE with Forest Fire burn rates. The model shows good agreement between calculated and experimental values for PBX-9404 and TATB (LASL), and VTQ-2 and Composition B (NOL). The calculations demonstrate the two-dimensional nature of the gap tests. This is particularly evident from the calculated distances of run to detonation in the test samples, which are significantly longer than those from the Pop plots at induced pressures near the critical gap length.
