Experimental and Numerical Investigation of the Deflagration of Energetic Materials at High Pressures

Abstract

The overall objectives of this program are (1) to develop new capabilities for the study of energetic materials combustion at ultra-high pressures from experiments that allow for direct observation of the combustion process and determination of ballistic parameters, and (2) to develop fundamental understanding of the multi-phase chemical mechanisms, thermochemistry, and equations of state necessary for predicting the combustion behavior at these extreme conditions. The research effort includes the parallel development of a mathematical model for a three-tiered system consisting of solid, liquid, and gas to be used to study the combustion of energetic materials up to pressures of 300 MPa, and the construction of an optically-accessible high pressure combustion chamber and strand burner for studying combustion phenomena of advanced energetic materials With recent advances in the understanding of both gas-phase and condensed-phase chemistries of energetic materials, the combined program will provide the framework for evaluating the predictability of existing and future energetic material combustion properties at extreme conditions.
