论VLW状态方程

Discussions on the VLW Equation of State

论述了VLW状态方程中爆轰产物分子势参数的确定;根据不同类型炸药爆轰性能参数计算结果对炸药爆轰产物碳在CJ态的相进行了分析讨论,认为不同的炸药,产物碳有石墨和金刚石两种相存在;将VLW状态方程和BKW状态方程进行了比较分析,指出了BKW状态方程与VLW状态方程的区别及其产生的原因,并给出了VLW状态方程计算含能材料(包括高能炸药、燃料空气炸药、民用炸药)的爆轰性能参数计算结果。结果表明,计算值与实验值符合较好。

The determination of the LJ potential of detonation products used in VLW EOS is introduced.The phase state of detonation product carbon under CJ condition has been discussed by comparing the calculated data with the experimental results.The main difference between VLW EOS and BKW EOS has been pointed out and the origin of this difference has been analyzed. The performance parameters calculated by VLW EOS of a wide range of energetic materials,including high explosives,fuel air explosives and civil explosives,is listed,and the calculations are in accord with the experimental data very well.
