Problems of Closing Models that Describe Detonation of Gas Suspensions of Ultrafine Aluminum Particles (Review)

Resumo

Various publications dealing with physicomathematical modeling ol detonation processes in gas suspensions ol line, submicron, and nano-sized aluminum particles within the framework ol mechanics ol continuous and heterogeneous media are reviewed. Important issues ol the description ol thermal dynamics, transport properties, and ignition mechanisms are discussed. Specific features of combustion regimes of micron- and nano-sized particles are considered. Closing relations for a semi-empirical model of detonation of suspensions of aluminum nanoparticles in oxygen are presented.
