SUPPLEMENTARY NOTES ABSTRACTThe development of models to compute the burning rate of energetic materials has undergone a paradigm shift in the last 15 years from treating the gas-phase reactions as a few global reactions to attempting to describe all of the elementary reactions involved. This shift toward chemical specificity has brought the promise of true predictive capability in such models. Thwarting this promise, however, has been the unattainability of treating the condensed-phase and surface processes with commensurate detail and assurance. In this work, it is shown that limited predictability has recently been achieved by a semiempirical finesse of the condensed-phase reactions and surface gasification through the agency of a universal pyrolysis law for certain families of propellant ingredients. It is also argued that the long-range prognosis for generalized predictability arising from a first-principles three-phase model lies with developing submodels for the condensed-phase and surface phenomena based on molecular dynamics (MD). However, since a continuum description of the gas-phase processes will always be preferable, the mating of these MD submodels with the continuum gas-phase description will be a non-trivial research issue. To facilitate the coming dialogue between current continuum modelers and future MD modelers, this work describes the conceptual and mathematical basis of the continuum models in considerable detail. It is suggested that the mating of these disparate descriptions might be accomplished by developing simple, idealized continuum submodels whose parameters and assumptions might be justified by the MD submodels. An example of such a continuum submodel is developed for the process of multicomponent evaporation as a surface-gasification mechanism. ii SUBJECT TERMS

Laser Ignition of a Low Vulnerability Propellant Based on Nitrocellulose: Effects of Ar and N2 Surrounding Atmospheres

“…Combustion phenomena of propellant are complex and involve several processes, such as decomposition, oxidation, phase conversion, species diffusion, etc. In this context, several research works have been published over the past decades to clearly understand the combustion of propellants [1][2][3][4][5][6][7][8][9][10][11].…”

“…They also made a database analysis to obtain the sensitivity of combustion rate on temperature [9]. In a recent work, Miller [10] studied in details several questions related to propellant combustion rate calculations from numerical models, highlighting the effect of chemistry in condensed phase. Cor and Branch [11] worked on flame kinetic chemistry on propellant surface in numerical models used until 1995.…”

A Novel Interior Ballistic Prediction of Gun Propellants Based on Experimental Pressure-Apparent Burning Rate Model in Closed Vessel

“…Classic interior ballistic method includes the form function and burning rate equations of gun propellants based on the geometrical burning rule, equations of projectile motion and energy conservation equation [1][2][3] . Except the chemical kinetics computing methods [4] , the burning rate of gun propellants is obtained by closed vessel test or gun firing, which is dependent on the pressure usually described by Vieille's law [5] It is well known that the derivation of propellant burning rate is based on the geometry of grains and parallel layer burning rule and expressed as Vieille's law. The Vieille burning rate is still used as a burning model of propellant in gun bore although it is bears no relation to thermodynamic process occurred in gun bore.…”

Energy Transfer at a Gas−Liquid Interface: Kinematics in a Prototypical System

“…This observation has stimulated the development of multiphase combustion models in which the gasification step is evaporation from this liquid layer, with the multitude of coupled combustion reactions then occurring exclusively in the gas phase. [1][2][3] Construction of a mathematically closed (1D) continuum model of these processes proceeds by the application of appropriate continuity equations for matter and energy at the phase boundaries, resulting in a formalism that has been remarkably successful in reproducing the burning rate of several practical propellants. Even with the demonstrated success of these continuum models, though, one ultimately would like to move toward a first-principles molecular model of the combustion process that would aid in the evaluation of prospective propellant materials.…”
