Abstract/ Foreword

Used the specialized software solution regarding to the thermochemical facilities, we can predict detonation (e.g. detonation velocity, pressure, energy, heat end temperature, etc.) and combustion (e.g. specific impulse, force, pressure, etc.) performance of energetic materials. The calculation of detonation parameters is based on the chemical equilibrium steady-state model of detonation. The equilibrium composition of detonation and combustion products is calculated by applying modified White, Johnson, and Dantzig’s free energy minimisation technique. The IT specialized application, named EXPLO5, uses the Becker-Kistiakowsky-Wilson (BKW) and Exp-6 EOS for gaseous detonation products, the ideal gas and virial equations of state of gaseous combustion products, and the Murnaghan equation of states for condensed products.
