Drew Lilly, Anubhav Jain, Ravi Prasher

AI总结:

本文将粗糙势能面转化为等效简谐振子,提出无可调参数的单原子液体热力学解析模型,准确预测熵、热容及相变潜热,并解释和修正相关经验规则。

摘要:

我们提出了一个利用粗糙势能面(PES)计算单原子液体热力学性质的解析模型。该PES被转化为等效的简谐振子。在不使用任何可调参数的情况下,该模型与单原子液体的实验熵、热容以及熔化和汽化潜热数据高度吻合。此外,它为Richard熔化规则提供了简单的物理解释,并为Trouton汽化规则给出了依赖于材料的修正。

英文摘要:

We present an analytical model for calculating the thermodynamic properties of monoatomic liquids using a rough potential energy surface (PES). The PES is transformed into an equivalent simple harmonic oscillator. Without employing any adjustable parameters, the model agrees closely with experimental entropy, heat capacity, and latent heat of fusion and vaporization data for monatomic liquids. In addition, it offers a simple, physical explanation for Richard Melting rule, and provides a material-dependent correction to Trouton Vaporization rule.
