The Behaviour of Detonation Waves in Single Phase Heterogeneous Systems.
Abstract
Most studies on the ignition and propagation of detonation waves are carried out with systems of uniform composition. However, fuel/air clouds, whether they are produced accidentally or deliberately, will exhibit varying degrees of inhomogeneity. The manner in which both flames and detonation waves propagate in such clouds has received scant attention in the past largely because of the difficulties, both experimental and theoretical, which such problems present. Because of the lack of information on the influence of gradients on wave behaviour it is often tacitly assumed in hazard analyses that the presence of concentration gradients will hamper rather than enhance the propagation of a detonation wave; but this assumption is by no means proven. The present study therefore aims at elucidating the fundamental mechanisms which control the behaviour of detonations in the presence of compositional variations. (Author)
