WebThe shock and detonation properties of the explosive PBXN-103 have been simulated with the use of the CTH hydrocode. These simulations require an unreactive Hugoniot relationship; a reactive equation of state (EOS) and a reactive rate law. One reactive rate law of interest is the Lee-Tarver ignition and growth model. To obtain parameters for the … WebIn this project an Eulerian-Lagrangian hydrocode was used to simulate the super compression detonation shock tube configuration with an inert core and a reactive multiphase core.
