- We previously developed a PETN thermal decomposition model that accurately predicts thermal ignition and detonator failure . This model was originally developed for CALORE  and required several complex user subroutines. Recently, a simplified version of the PETN decomposition model was implemented into ARIA  using a general chemistry framework without need for user subroutines. Detonator failure was also predicted with this new model using ENCORE. The model was simplified by 1) basing the model on moles rather than mass, 2) simplifying the thermal conductivity model, and 3) implementing ARIA’s new phase change model. This memo briefly describes the model, implementation, and validation.
