Detonation Calculations With a Percus-yevick Equation of State.
NTIS: PB 234 074 :15 pages
Chapman-jouguet detonation calculations were carried out for pentaerythritol tetranitrate (petn), tnt, and ammonium nitrate-fuel oil (AN-FO) explosives using the compressibility form of an equation of state of hard spheres based upon percus-yevick (py) theory, and a chemical equilibrium detonation code called tiger. Similar calculations were also carried out with the becker-kistiakowsky- wilson (bkw) equation of state. For petn, the bkw equation gives somewhat better agreement with experimental values of detonation velocity and pressure. However, in terms of experimental temperatures and concentrations of the minor product species (no), the predictions of the py equation are shown to be more satisfactory. Similar comparisons of experimental and theoretical results for tnt and AN-FO indicate that the py equation has general utility in predicting the detonation properties of condensed explosives at moderate loading densities (po<1.3 G/cm3).
