On Oscillatory Instability in Convective Burning of Gas-Permeable Explosives

I. Brailovsky, M. Frankel, L. Kagan, G. Sivashinsky (2010)

Mathematical Modelling of Natural Phenomena

Similarity:

The experimentally known phenomenon of oscillatory instability in convective burning of porous explosives is discussed. A simple phenomenological model accounting for the ejection of unburned particles from the consolidated charge is formulated and analyzed. It is shown that the post-front hydraulic resistance induced by the ejected particles provides a mechanism for the oscillatory burning.

Oscillatory Propagation of a Rich Premixed Spray Flame

L.S. Kagan, J.B. Greenberg, G.I. Sivashinsky (2010)

Mathematical Modelling of Natural Phenomena

Similarity:

Experimental evidence points to a rich variety of physical scenarios that arise when a laminar flame propagates through a pre-mixture of evaporating liquid fuel and a gaseous oxidant. In this paper new results of time-dependent numerical simulations of rich off-stoichiometric spray flame propagation in a two-dimensional channel are presented. A constant density model is adopted, thereby eliminating the Darrieus-Landau instability. It ...
