AWSD calibration for the HMX based explosive PBX 9501

Abstract

A calibration of the AWSD (Arrhenius Wescott-Stewart-Davis) reactive flow model, applied to the HMX based explosive PBX 9501 is presented. Requisite equation of state parameters for the high explosive reactants and products are based on a combination of experimental data and theoretical calculations. The experimental data needed to calibrate the reaction rate model, specifically shock to detonation transition and detonation propagation at a variety of initial temperatures, are presented along with model results and planned future activities.
