AWSD Reactive Flow Model and Davis Equation of State Calibration for XTX 8004

This work details the calibration of the AWSD (Arrhenius Wescott-Stewart-Davis) reactive flow model and the Davis reactants and products equation of state for the RDX based extrudable high explosive XTX 8004. The calibration of the Davis reactants and products EOS made use of data from various sources including experimental data and thermochemical data generated using the LANL code, Magpie. The AWSD rate law parameters were calibrated to shock-to-detonation data obtained from embedded magnetic gauges and to diameter effect data obtained using the Shock Wave Image Framing Technique (SWIFT). Results of the calibration were validated using simulations conducted in a LANL hydro code.
