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