MULTI-CHANNEL PDV AND RAMAN
Abstract
The University of Rhode Island (URI) Energetic Materials Lab conducts a number of studies on military projects. New energetics materials and formulations introduce heterogeneity on the micron and nanometer scale. Small-scale experiments have been done to aid development of models to predict performance at munition scale. Munitions and their compositions can be modeled using multiphysics codes such as those developed by national labs (ALE3D or CTH), but the number of elements and resolution of any models generated are limited severely by the computational bandwidth available. Most of our projects require modeling, characterization of performance, i.e. detonation, and reaction products. As we push the scale of the tests down, more sophisticated characterization tools are required. The request here is for a multi-channel photon Doppler velocimetry (PDV) to follow detonation in the formulations of interest and a fiber-coupled Raman spectrometer to facilitate research into determining the shock temperatures and reaction zone compositions of energetic materials. Our intention is to use this instrument for analysis of small, multi-gram samples.
