“…Kauffman et al (1982Kauffman et al ( , 1984, observed that a spinning type of detonation wave was established in hybrid methane-air coal dust mixtures. The structure of the wave was found to be similar to that reported for pure methane-air mixtures by Wolanski et al (1981). It was also found that by increasing the coal dust concentration both the lean and rich detonation limits are initially lowered.…”

“…A surprising result, which is the subject of the present paper, is that the addition of relatively small amount of combustible organic dust to methane air mixtures can significantly increase the detonability of such mixtures. The present paper describes a study of detonations propagating in suspensions of oats dust in methane/air mixtures just on either side of stoichiometric (9.5% by volume), a gaseous explosive known to be relatively difficult to detonate (Wolanski et al, 1981). The experimental setup used to investigate this phenomenon is first described below followed by a presentation and then discussion of the experimental results.…”

“…Note that the vertical scale is 1/d, where d is the scale of the experimental apparatus, here the tube diameter. Experimental data are by Matsui (2002), Wolanski et al (1981), and Kogarko (1959). for methane/air mixtures at 1 atm as a function of mixture composition.…”

“…The sup-pression of gaseous detonation by a fine inert dust was first reported by Laffitte and Bouchet [44], but the influence of relatively large inert particles on the initiation and propagation of gaseous detonation was studied only recently [28], [45][46][47][48]. Wolinski et al [45] showed that the addition of relatively large inert particles speeds up transition to detonation.…”
