Particle force model effects in a shock-driven multiphase instability

Evaporation and breakup effects in the shock-driven multiphase instability

“…Several investigations have been conducted through simulation and experimentation to explore the effect of particle lag (velocity relaxation time) on shock-driven multiphase mixing. Simulation efforts [4,5,11,12] showed that the vorticity deposition and mixing decrease as particle relaxation times increase. Thus, large particles resulted in a lower interface development and mixing.…”

“…In addition, the paper highlighted the importance of the particle size distribution when estimating the development of the hydrodynamics instabilities in the flow. Black et al [12] presented a comparison between the classic RMI (dusty gas case) and three different particle size cases. It was noted that the strength of the vorticity reduces with increasing particle size.…”

Heterogeneous/particle-laden blast waves

“…They systematically vary the gas-solid coupling mechanism to determine the primary mechanism responsible for jet formation. Black et al [45] also present numerical simulations of a shock-driven multiphase instability, by considering the interaction of a shock wave with a circular region dilutely seeded with particles. They consider the effect of different particle force models on the development of the instability.…”

“…Examples of the use of the two continuum models listed in Table 1 in which the solid phase is treated in a Lagrangian manner are represented by papers in this thematic issue [44][45][46][47][48][49].…”
