采用L-J(Lennard—Jones12—6)势函数,结合VLW状态方程,计算了水的冲击压缩Hugoniot曲线。将理论计算结果与实验结噪进行了比较,当势函数参数ε/K=120、b0=30.42时,计算值与实验符合较好。与采用BKW状态方程计算结果相比,VLW状态方程能够更准确地描述水的冲击Hugoniot曲线。
With the L-J (Lennard-Jones 12-6) potential function, the shock Hugoniots of water were calculated by using VLW equation of state. The calculation results agree well with the experimental data when the potential parameter e/Kis 120 and b0 is 30.42. VLW EOS can characterize the shock Hugoniot of water more accurately than BKW EOS.
