Embodiment

[0067] Application of the VLW Program

[0068] Applying VLW program to calculate the detonation parameters of liquid explosives is a very important issue for the given initial input values. The initial input values ​​that must be given are: the chemical composition of liquid explosives; the formation enthalpy of each component of liquid explosives; Density of liquid explosives.

[0069] The density of liquid explosives is calculated based on the weight percentage of the given fuel, combined with the ambient pressure and temperature.

[0070] Applying the VLW program to calculate the detonation parameters of liquid explosives, the following assumptions need to be made. The reaction system is regarded as a premixed combustible mixture of all gaseous equivalents. In order to compensate for the heat required for evaporation, the enthalpy of formation of the fuel here uses liquid The enthalpy of formation, the initial temperature T 0 is 298.14K, the initial pressure P 0 for 1atm...

Abstract

The invention relates to detonation parameters of liquid explosive and provides a method for calculating CJ detonation pressure, detonation speed, detonation temperature and specific volume of the liquid explosive through a thermodynamic function of compounds and a minimal free energy method, and the invention belongs to the technical field of energetic materials. A VLW program is created on the basis of a BKW program and is used for calculating such function relations of the liquid explosive as CJ detonation pressure, detonation speed, detonation temperature, specific volume and the like through the thermodynamic function of compounds by utilizing the minimal free energy method.

Description

technical field [0001] The invention relates to detonation parameters of liquid explosives, which is a method for calculating CJ detonation pressure, detonation velocity, detonation temperature and specific volume of liquid explosives through thermodynamic functions of compounds and minimum free energy, and belongs to the technical field of energetic materials. Background technique [0002] The calculation of detonation parameters of liquid explosives has important guiding significance for the understanding of liquid explosives. However, considering that the detonation of liquid explosives belongs to heterogeneous detonation or heterogeneous detonation, especially that liquid explosives have both the characteristics of volume explosion and the characteristics of point explosion, so it is a special detonation process. This is the difference between it and condensed explosives and hydrocarbon fuel mixed with air to cause detonation. [0003] Some liquid compounds or their mix...
