The flame propagation parameters of aluminum nanopowder in the bulk layer were investigated. The aluminum nanopowder produced by the method of the electrical explosion of wires used in this study. The aluminum bulk layer was ignited by open flame, heated body, or electric spark. The flame propagation behavior is described as a two-stage process: 1) flame propagation over the surface layer and deep into the sample; 2) the thermal explosion mode. It was found that the type of ignition source influences the parameters of the first stage of the combustion. The minimum ignition energy for the aluminum nanopowder bulk layer was measured. The effect of the bulk layer inclination angle on flame propagation parameters was determined. The obtained results can be useful in assessing the fire hazard and organizing safe processes of industrial production during the use, storage, handling, and transportation of metal nanopowders.

铝纳米粉体层中的火焰传播行为

研究了铝纳米粉在块体层中的火焰传播参数。通过本研究中使用的电线的电爆炸方法生产的铝纳米粉。铝块层被明火,加热的物体或电火花点燃。火焰传播行为被描述为两个阶段的过程:1)火焰传播遍及表层并深入样品。2)热爆炸模式。发现点火源的类型影响燃烧的第一阶段的参数。测量了铝纳米粉体层的最小点火能量。确定了本体层倾斜角对火焰传播参数的影响。
