Simulation of Detonation Propagation in Turbulent Gas-Solid Reactive Mixtures

The present study focuses on the simulation of highly reactive two-phase flows associated with detonations. A hybrid scheme, that combines a high-order shock-capturing method and a second/fourth-order accurate, low dissipation scheme is first validated by simulating blast wave discharges and shock-vortex interaction. The Large-Eddy Simulation model used in the present formulation is considered afterward in a fundamental study of shock-turbulence interaction. The solid phase tracking algorithm is then validated in supersonic environment. Finally, a detonative mixture composed of H2/O2/Ar, similar to an experimental configuration, is simulated with and without the presence of solid aluminum particles. The explicit role of the particles in this environment is considered, and the presence of a Double− Fronted Detonation is analyzed.
