Title: Thermal response of explosives subjected to external heating. [TNT, Comp. B, HMX, TATB, DATB, and NQ]

Abstract

A series of unconfined one-dimensional heating experiments in slab geometry was conducted with TNT, Comp. B, plastic-bonded HMX, TATB, DATB, and NQ. The explosive samples were heated on one surface at heating rates between 10 and 25/sup 0/C/min. The experimentaly determined times and temperatures to ignition were reproduced computationally, with one exception, by solving a one-dimensional heat-conduction equation containing a zero-order reaction energy source term and a time-dependent temperature boundary condition. The one exception was plastic-bonded NQ. Unconfined plastic-bonded NQ did not ignite under the experimental conditions used. The heat-transfer mechanism in molten TNT, as expected, was convective; and for molten Comp. B, conductive. A reactive heat-transfer program, EXPLO, was written that is capable of solving the convective transfer mode and accepting mixtures of explosives reacting with first-order kinetics.
