Characterization of initiation and detonation by Lagrange gage techniques. Final report
The theoretical work in this report is concerned with a reactive flow Lagrange analysis (RFLA) for shocked explosives that was formulated and developed at SRI International and Lawrence Livermore National Laboratory (LLNL). This RFLA takes a set of Lagrange particle velocity and pressure histories recorded in shocked explosive as input and calculates the flow fields in the explosive and its global rate of decomposition. A similarity solution modeling a type of initiation observed in PBX9404 and incorporating a realistic description of shocked explosive was constructed to provide a means of testing the computational procedures used in the RFLA. These procedures and the RFLA were validated in test calculations performed with the similarity solution at LLNL.
