NEW EQUATION OF STATE FOR DETONATION PRODUCTS

Many experimental and theoretical problems exist in obtaining the equation of state (EOS)for products of detonation or propellants. Because there are not sufficient availableexperimental data, the computational methods must be applied to derive such an equation. Inthis work, a new EOS is derived for detonation products based on statistical thermodynamics,and used to calculate the P-V-T properties of some explosive materials. Our derived EOS ismore general than the previous equations, such as JCZ EOS, specially, the last version of JCZEOS, namely JCZ3, may be obtained using some approximations on our model.
