Abstract: The large-scale explosive dispersal and the unconfined detonation of particle-spray-air ternary mixtures are closely
related to industrial accidents and military applications. However, most of the existing research focuses on the small-scale
experiment in the laboratory, with large-scale explosive dispersal experiments being relatively scarce. The initiation state of the
aerosol cloud determines the blast power, and the device structure and specific explosive charge are the main factors affecting
the cloud morphology. To study the damaging effect of aerosol, the large-scale dispersed experiment of 125 kg fuel was carried
out. The process of aerosol development was observed by high-speed video recording. Variation characteristics of FAE cloud
with different canisters and the specific central explosive were studied. The aerosol diameter and height were used to
describing the aerosol shape, then they were analyzed under different initial experiment conditions. Three types of canisters
were utilized, namely the basic canister, the compound canister, and the strengthen canister, with the primary difference being
their radial restraint mechanisms. The specific central explosive was adopted the T-shaped charge. The results show that the
aerosol formation is reliable through the replication experiments. Because of its strong radial restraint, the compound canister

has the advantage in the aerosol diameters. The aerosol diameters of compound canister can reach 25.5 m, compared to strong
