Optimization and Application of Equations of State for Detonation Condensed Carbon Products

• • NDGP EOS improves TATB detonation velocity prediction by 1.5%-2.5% and detonation pressure by 1.5%-4% compared to Fried and Cowan-Fickett EOS, enabling more reliable performance evaluation for TATB-based formulations. • • NOCP EOS enhances BTF detonation pressure prediction by 3%-5% relative to legacy EOS, with velocity accuracy comparable to Fried EOS but superior to Cowan-Fickett, critical for high-detonation-temperature explosives. • • Danilenko EOS for disordered low-density carbon improves LTNR detonation velocity prediction by 3%-7% across loading densities from 0.93 to 3.1 g·cm⁻³, addressing the weak initiation regime where conventional models fail. • • The new EOS are derived from molecular dynamics-based physical models, eliminating reliance on empirical fitting to detonation data, thus providing a generalizable framework for predicting performance of novel energetic materials.
