摘 要:对在Ni Si、Ti Ni和铝热反应体系中的螺旋燃烧进行了实验研究与观察。主要研究了Ni Si系统中原始化学配比、坯体的原始密度、硅颗粒尺寸及起始温度对螺旋燃烧工艺的影响以及Ti Ni系统中预热温度及原始化学配比对燃烧工艺及模式的影响。结果表明:螺旋燃烧是一种非稳态燃烧,弱的放热反应或反应中的热量损失可能导致燃烧源的不稳定,强化反应过程(如预热)能够改变燃烧模式,使非稳态螺旋燃烧向稳态燃烧转变。The experimental investigation and observation on the spin combustion in Ni-Si, Ti-Ni and thermite systems were presented. The effects of the initial stoichiometry, initial density, particle size of silicon, and initial temperature on the spin combustion process were studied mainly in Ni-Si system. In Ti-Ni system, the effects of preheating temperature and initial stoichiometry of compact on combustion process and mode were studied. The results show that the spin combustion is one of the non-steady state combustion. Weak exothermic reaction or heat loss in the reaction can result in the non-stability of combustion wave. Strengthening the reaction process such as preheating can change combustion mode from unstable spin combustion to stable one.
