Aluminized explosives exhibit excellent performance because the oxidation of aluminum (Al) powders enhances the pressure and temperature of detonation products. However, the equation of state (EOS) of detonation products has not been understood well. In the present study, we conducted long-time tests (approximately 1 ms) of a metal rod driven by detonation products of RDX, RDX/LiF, and RDX/Al. In addition, we used laser velocimetry (PDV) to measure the freesurface velocity of the rod. Thermochemical code DLCHEQ was successfully applied to the hydrodynamic program SSS to perform the rod-driven test, and a novel method was established to study the EOS of detonation products from the perspective of composition. The reliability of DLCEHQ was validated by a small deviation ( |
