氦的状态方程
An Equation of State for Helium
摘要:
本文提出了一个新的氦的状态方程。PANDA代码用于构建固相和液相的单独EOS表。然后使用PANDA相变选项将固体和流体EOS组装成多相EOS表。热电子激发和电离的贡献也包括在模型中。状态方程与所有静态和冲击波数据非常一致,除了在温度低于20K时,需要进一步的工作。这个EOS主要是为巨行星、太阳和恒星的模型而开发的,但在其他应用中也应该很有用。
英文摘要:
This report describes a new equation of state (EOS) for helium. The PANDA code was used to construct separate EOS tables for the solid and fluid phases. The solid and fluid EOS were then assembled into a multiphase EOS table using the PANDA phase transition option. Contributions from thermal electronic excitation and ionization were also included in the model. The EOS gives very good agreement with all static and shock-wave data, except at temperatures below 20K, where further work is needed. This EOS was developed primarily for use in models of the giant planets, the sun, and stars but should be useful in other applications as well.
