Instability of detonation waves in FEFO/methanol solutions

Combustion, Explosion, and Shock Waves Aims and scope

Abstract

A VISAR interferometer and a high-speed streak camera are used to study the structure of detonation waves in bis-(2-fluoro-2,2-dinitroethyl)-formal (FEFO) mixtures with methanol, whose mass concentration varied in the range of 0–35%. It is shown that the two types of instability existing in liquid explosives, which are the one-dimensional instability of the detonation front and the reaction failure wave instability on the edge of the charge, can be implemented in any combination. The reaction time of the studied mixtures is determined, and the different character of the dependence of the critical diameter of detonation and the reaction time on the diluent concentration is demonstrated.
