Aluminized highly energetic materials simulation under partial chemical equilibrium assumption with HEMSim

Abstract. We are pleased to introduce the first version of EUDETCODE, an advanced computational code for ideal detonation analysis, capable of handling the presence of aluminum in high-energy reactants. The hard coded model incorporates the variable percentage of aluminum reaction completion during detonation, reflecting its influence on the detonation process. Key outputs include the Chapman-Jouguet (CJ) point and the fitting of the Jones-Wilkins-Lee (JWL) equation of state, both of which are validated against experimental results. The validation demonstrates the code's accuracy and reliability in predicting detonation behavior for energetics containing reactive metals.
