摘要
总结并对比了气动悬浮、电动悬浮、磁悬浮、光悬浮和声悬浮这5种常重力环境下悬浮技术的特点,在此基础上综述了近年来固体燃料颗粒以及液体燃料液滴的悬浮燃烧研究进展。指出悬浮燃烧技术消除了样品和载体之间的接触热传导,有利于从微观尺度上准确描述燃烧过程中物质的变化和能量的释放规律,获取物质的本征燃烧特性。在多种悬浮技术中光镊悬浮具有材料适用范围广、可精确操控颗粒/液滴悬浮位置、悬浮稳定性好以及便于集成等优点,是含能材料燃烧领域中最具有应用前景的一种。未来工作中建议加强单颗粒/液滴燃烧过程产物化学组成表征、扩展悬浮燃烧技术在含能材料领域中的应用范围以及开展含能材料多颗粒、多液滴的燃烧特性及相互作用机理研究。附参考文献44篇。
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.
