Extended JCZ3 Equation of State and JAGUAR Implementation for High Explosives
Abstract
An extended JCZ3 based equation of state for the modelling of high explosive detonation products has been implemented in the JAGUAR computer model. This development includes the parameterization of EXP‐6 potentials for individual products species, as well as mixing rules for the combination of species. Non‐linear variable metric optimization was used for the species parameterization, as well as for the solution of free energy minimized states. Explosive detonation and products expansion are typically modelled for JWL and JWLB high explosives thermodynamic equation of state development. An analytic c ylinder test model was developed for the comparison to experimental cylinder expansion test data and for the characterization of explosive products expansion and work output. Examples and comparisons to data are presented. Historically, streak photography was used for cylinder testing, whereas photon‐doppler velocimetry (PDV) is now standard. This has resulted in some changes in cylinder testing data reduction. A JAGUAR MSIAC web‐based application is currently under development for use by the MSIAC member nations.
