High explosives (HEs) store a great deal of chemical potential energy that, upon decomposition, can burn at low pressures like a candle or detonate at pressures and temperatures that are comparable to the center of the earth. Reactive flow modeling attempts to devise relatively simple rates of chemical decomposition and how these rates couple to both thermodynamics and hydrodynamics. During this talk, the set of challenges that face reactive flow modeling will be outline, followed by a typical set of experiments utilized for model calibration. A brief history of previous models developed at Los Alamos and other national/international laboratories will be given, as well as the recently devised Arrhenius WSD (AWSD) model. An envisioned path towards greater predictive capabilities, going beyond what is possible today, will also be outlined.
