Shock interactions with a dense-gas wall layer

Dynamics of dust dispersion from the layer behind the propagating shock wave

“…The work of Korobeinikov, Markov, and Menshov (1986), Korobeinkov et al (2002), Kuhl et al (1989), Kuhl, Reichenbach and Ferguson (1992), Fedorov and Gosteev (2002), Fedorov, Fedorova, Fedorchenko, and Fomin (2003), Klemens et al (2001a), Klemens et al (2001b), Klemens, Kosinski, and Oleszczak (2002) and many others may be cited.…”

Dust entrainment by means of a planar shock induced vortex over loose dust layers

“…3 and 4, resembles the surface instabilities which were photographed by Borisov et al (1967). Kuhl's (1990Kuhl's ( , 1992 calculations show many vortices of similar shape.…”

“…Ben-Dor and Rayevsky (1994) investigated a similar problem both numerically and analytically. Since as mentioned earlier, a fluidized bed can be considered as a dense "pseudo-gas", it is the author's belief that the studies of Kuhl et al (1992) and Ben-Dor and Rayevsky (1994) could assist in better understanding the interaction phenomenon of planar shock waves with loose dust layers, and the dust entrainment mechanism as a consequence of this interaction. It has been shown by Ben-Dor and Rayevsky (1994) that the resulted wave configuration can be either a regular reflection (Fig.…”

“…Thus the pressure t9o of the fluidized bed is, in fact, equal to the pressure of its gaseous component, i.e., Pg" Kuhl et al (1992) investigated both experimentally and numerically the interaction of planar shock waves with a dense gas layer. The dense gas in their investigation was Freon-12.…”

Numerical simulation of a viscous vortex ring interaction with a density interface

“…Greenough and Bell,22 using the compressible version of this methodology, have calculated the transition to turbulence in a shock induced mixing layer, showing excellent agreement with shock tube experiments at the Ernst Mach Institute. 23 For the ring-interface interaction, there is very little quantitative data available. The experiments of Dahm et al 1 were primarily qualitative, and in a different flow regime than our calculations.…”
