    Abstract
  • The equation of state of detonation products for RDX explosive at different initial densities is calculated by adopting the program based on the statistical physics model.It is found that only gas phase product generates after the explosive detonation when the initial density of explosive is less than 1.20 g/cm3.With the increasing of initial density of explosive, solid carbon dissolves out after the explosive detonation.When the initial density of explosive is less than 1.60 g/cm3, the calculated detonation velocity and detonation pressure is in good consistent with the experimental value regarding the gas phase product as uniform mixing.With the increasing of initial density of explosive, the calculated detonation velocity and detonation pressure deviate largely from the experimental value.After detailed analysis, we find out that there is a supercritical fluid phase separation in this condition.Considering this effect in our program, a good result is obtained.
