单颗粒/液滴燃料悬浮燃烧研究进展

The features of five levitation technologies in normal gravity environment, namely pneumatic levitation, electric levitation, magnetic levitation, optical levitation and acoustic levitation, were summarized and compared. The research progress of combustion of levitated solid fuel particles and liquid fuel droplets in recent years were well reviewed. It is pointed out that levitation eliminates the heat conduction between the sample and the carrier during combustion, which is desired to capture the relatively accurate information about the evolution of substances and the release of energy at the microscopic scale, and obtain the intrinsic combustion characteristics of substances. Among the above-mentioned levitation technologies, optical levitation has the advantages of wide application range of substance, precise control of the levitation position of particles/droplets, good levitation stability and easy integration with other diagnostic devices, and is the most promising one in a variety of levitation techniques in the field of combustion of energetic materials. In future work, it is proposed to strengthen the characterization of the chemical composition of the products of the single-particle/droplet combustion process, expand the research scope of levitation combustion technology in the field of energetic materials, and carry out research on the combustion characteristics and interaction mechanism of multi-particle and multi-droplet energetic materials. 44 References were attached.
