Detonation waves are self-sustained supersonic reaction waves, which can be sustained in reactive gases and condensed phase energetic materials (propellants, explosives, dusts, etc...). The large overpressures occurring behind gaseous detonations make them useful for propulsion applications. These applications require accurate control of the wave initiation and wave stability. For safety applications, whenever a detonable gas is accidentally released, it is desirable to have the capability for predicting the eventual ignition and propagation limits and the large-scale effects in order to develop the appropriate mitigation strategies. Unfortunately, the detonation wave dynamics cannot be predicted in typical engineering applications. The present research's objective is to develop such a predictive model.
