N2 - We discuss equation of state forms used to describe condensed high explosive materials that are comprised of mixed components of reactants and products. We show that when the equations of state have poor thermodynamic properties, or good properties but used outside their calibration domain, reactive flow simulations can fail unexpectedly, due to either no states or multiple found thermodynamic states. We propose the use of complete equations of states for components to build multi-component equations of state for explosive mixtures. Specific examples of equation of state forms are given that show both simulation failure and success, when well-posed equation of state forms are used to simulate blast generated by the initiation of an explosive from an intense high-pressure source.
