The dispersion of oxidized Al nanoparticles into clusters by rapid heating in a shock wave has been studied. Cluster distribution characteristics were calculated as a function of the parameters of the initial nanoparticle distributions and the nature of the interaction of deformation waves with the nanoparticle shell and core. The studies were carried out using the author’s proposed resonance mechanism for the dispersion of the liquid core of a nanoparticle by the shock pulse from the destruction of the solid oxide shell. The ignition of Al nanoparticles after dispersion in air was analyzed using the previously described kinetic oxidation mechanism with the evaporation of clusters taken into account. Initial distributions of nanoparticles and their ignition times are validated against published experimental data.

铝纳米粒子在冲击波中分散过程中铝团簇的分布及其在空气中的点火

已经研究了通过在冲击波中快速加热将氧化的 Al 纳米粒子分散成簇。簇分布特征计算为初始纳米粒子分布参数和变形波与纳米粒子壳和核相互作用的性质的函数。这些研究是使用作者提出的共振机制进行的，该共振机制通过来自固体氧化物壳的破坏的冲击脉冲分散纳米颗粒的液体核。使用前面描述的动力学氧化机制分析了在空气中分散后的 Al 纳米粒子的点火，并考虑了团簇的蒸发。纳米粒子的初始分布及其点火时间已根据已发表的实验数据进行验证。
