Influence of particle non-dilute effects on its dispersion in particle-laden blast wave systems

Even though the interaction of blast waves with dense particle distributions is ubiquitous in nature and industry, underlying physics multiphase system evolution not clearly understood. A canonical composed an embedded monodisperse distribution spherical particles a spherical, high-energy gaseous charge studied numerically using Eulerian–Lagrangian approach to elucidate role non-dilute effects on dynamics two-phase flow system. The direct simulation Monte Carlo method modified model inelastic particle–particle collisions inter-leaving through complex structures obtain parameters that are fit semi-empirical cloud drag laws account for aerodynamic interactions. study reveals inter-particle decrease total kinetic energy at early stages particle-laden wave evolution, but near-particle increases this stage. In contrast, later tend retain more energy, while interactions dissipate energy.
