Transition state theory applying to the study of reaction processes in detonation.

摘要

The presence of a nearly constant process time that characterizes the fast reaction portion found in the detonation of condensed high explosives can be explained by the transition state theory. Through hydrodynamic modeling, we identify that time as the excitation time for the production of an energetic state that can go either forward to achieve decomposition or backward to the original unexcited state. The energetic state is a representation of a nonequilibrium condition that favors the chemical reaction, whereas the unexcited or equilibrium state does not. This process time is determined by matching the experimental interface velocimetry record, and its value is nearly constant over a wide range of conditions. 23 refs., 6 figs.
