"Predictability of detonation wave phenomena: influence of diffusive processes, hydrodynamic instabilities and relaxation effects on the hydrodynamic description"

爆轰波是一种自持的超音速反应波，可以在反应气体和凝聚相含能材料(推进剂、炸药、粉尘等)中持续存在。气态爆轰后产生的巨大超压使其适用于推进应用。这些应用需要对波浪起始点和波浪稳定性进行精确控制。对于安全应用，每当意外释放可爆气体时，都希望能够预测最终的着火和传播极限以及大规模影响，以便制定适当的缓解策略。遗憾的是，在典型的工程应用中，爆轰波动力学是无法预测的。本研究的目的就是开发这样一个预测模型。

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.
