Development and Application of VLW Equation of State for Detonation Products

Based on the internationally recognized perfect VIRIAL equation of state,the equation of state for detonation products of VLW explosives was established.The formation background of the equation of state for detonation products of VLW explosives was briefly described,and the derivation process of VLW equation was presented.The detonation performance parameters of military high explosives,civil industrial explosives,condensed phase explosives and gaseous fuel air explosives were calculated by using VLW equation.The thermodynamic functions of detonation products(internal energy,entropy,chemical potential,etc.)were derived.The results show that the parameters calculated by VLW equation are accurate and reasonable,and the calculation problem of advanced VIRIAL coefficient at high temperature(T*>20)is successfully solved,and the properties of VIRIAL equation under detonation condition are accurately expressed.
