摘要:
建立了铝粉—空气两相爆轰的一维模型,采用CE/SE方法对铝粉燃烧转爆轰过程进行数值模拟.分析了铝粉尘爆轰管内流场,研究了不同位置处铝粉颗粒半径随时间的变化规律.讨论了点火能量对铝粉燃烧转爆轰过程的影响.结果表明:点火能量越低,形成稳定爆轰距离越长.本文的数值计算结果对铝粉尘爆轰研究具有重要的理论指导意义.
Abstract:
Uni-dimension two-phase model of aluminum dust-air detonation is created. Deflagration to detonation transition process of aluminum dust is numerical computated by using CE/SE method. Internal flow field of aluminum dust detonation tube is carried out. The variations of aluminum particle radius with time at different positions are studied. And the effects of ignition energy on deflagration to detonation transition process of aluminum dust are discussed. The results show that the lower the ignition energy,the longer distance to form a stable detonation. All the numerical results here provide some theoretical foundations for aluminum dust detonation research.
