High-speed
combustion of gaseous reactants displays a variety of phenomena,
including flame acceleration, deflagration-to-detonation transition
(DDT), detonation instability, and quenching. The equations
of reactive gasdynamics provide a reasonable model for a study
of these phenomena. The state of affairs is far from satisfactory
for condensed-phase explosives, however. The range of observed
behavior is substantially broader for this class of materials,
especially when these are in a granular or porous form. Deflagrations
can travel at elevated speeds, the materials are more sensitive
to applied stimuli, and there is an increased propensity for
DDT. The mechanical response of the material is richer, and
it couples strongly with the confinement, the chemistry, and
the energetics to determine the course of combustion.
The recognition that porosity may appear unintentionally (through
degradation over time or through accidental damage), and lead
to unexpected behavior, has lent some urgency to the need for
improved quantitative understanding of the manner in which energetic
materials combust. Considerations of safety demand, in particular,
the capacity to identify the mechanical or thermal loadings
that will, or will not, lead to a detonation.
When a detonation IS the desired goal, there is the need to
determine, precisely and economically, the locus of the detonation
front, especially as it negotiates corners and obstacles, or
propagates through ducts of varying cross section.
This workshop will bring together experimental scientists, theorists
currently developing continuum, micromechanical as well as molecular
models, applied mathematicians exploring the structure and properties
of the models, as well as experts devising and implementing
appropriate computational strategies. The aim is to describe
current approaches, identify recent successes, and highlight
the challenges that remain in the general area of combustion
of energetic materials.
Although
the main emphasis will be on the condensed phase, issues relating
to high-speed combustion in gaseous materials will receive attention
as well.
