Shock-Particle Curtain Interactions at High Mach Number

Shock-Particle-Interaction Study with a Hyperbolic Two-Fluid Model

“…The well-established experimental setup for shock-particle interactions developed at SNL is used as a reference to explore the modeling of drag, added mass and pfp pressure. A cross-sample of two experimental campaigns from [6] and [38] is used to explore a large range of shock Mach numbers, particle concentrations and material densities. 10: Effect of pfp pressure on trajectories of upstream and downstream edges of a curtain composed of 316 stainless steel particles for M s = 1.4 (a), M s = 1.55 (b) and M s = 1.7 (c).…”

“…The experimental setup of reference is the SNL multiphase shock tube, which has been used for a decade [37] to study shock-particle-curtain interactions in the dense regime. It has the advantage to provide the most recent measurements over a wide range of material density, high-speed flow regimes (from supersonic [6] to hypersonic [38]) and gas-solid regimes. In the experiment, the shock tube is filled with a high-pressure gas (driver gas) and a gas at ambient conditions (driven gas).…”

“…The domain is defined as [−L/2, L/2]. The data used in this work [6,38] have the advantage of compiling a wide range of material densities, curtain widths, particle concentrations and gas-flow regimes. Indeed, the most recent configurations have supersonic shocks, which have not yet been studied extensively.…”

“…This has already been discussed in [15] where several α p isocontours are displayed, which correspond to very different curtain-edge evolution with time. In the two references used here [6,38], the curtain edges were taken as 95% of the maximum pixel intensity. Here, the same metric is used where the pixel intensity corresponds to the maximum volume fraction in the domain at a given time.…”

A Kinetic-Based Model for High-Speed, Monodisperse, Fluid–Particle Flows

“…These works have been followed up by numerical studies to assess different multiphase flow models [28,35,41]. More recently, these studies have been extended to hypersonic flows [54] and underwater shocks [2].…”
