DETONATION PRESSURE MEASUREMENTS ON PETN

摘要: PETN is widely recognized as an example of nearly ideal detonation performance. The chemical composition such that little or no carbon produced in the products. reaction zone width less than currently detectable. (<1 ns) Observations on have thus become a baseline for EOS model predictions. It has therefore important to characterize parameters accurately possible order provide most exacting comparisons predictions with experimental results. We undertook painstaking review pressure measurements reported earlier work was presented at Fifth Detonation Symposium and found corrections were required determining shock velocity PMMA witness material. also refined impedance calculation account difference between usual ''acoustic'' method more accurate Riemann integral. Our indicates CJ pressures previously full density require average lowering about 6 percent. lower densities progressively smaller corrections. present analysis records, supporting hydrodynamic simulations, integral results, parameter values derived from revised
