摘要

提出了一个简单的含悬浮铝粒子的氧、氢、氩混合爆轰的数学模型。该模型基于多相介质力学的方法和还原化学动力学方程来描述气态和非均相反应。考虑以纳米颗粒的形式生产氧化铝。分析了平面通道中细胞爆轰的起爆和传播问题。计算结果表明，少量可燃颗粒的加入会导致爆速的增加和细胞结构的转变。

DEVELOPMENT OF A MODEL OF HYBRID DETONATION IN A MIXTURE OF OXYGEN-HYDROGEN-ARGON AND ALUMINUM PARTICLES

A simple mathematical model of hybrid detonation in oxygen-hydrogen-argon mixtures with suspended aluminum particles is suggested. The model is based on the approaches of the mechanics of multiphase media and equations of reduced chemical kinetics to describe gaseous and heterogeneous reactions. Production of alumina in the form of nanoparticles is considered. The problem of initiation and propagation of cellular detonation in a planar channel is analyzed. The results of calculations show that addition of small amount of combustible particles leads to increase in the detonation velocity and transformation of the cellular structure.
