Abstract

The Vliegenthart-Lekkerkerker relation for the second virial coefficient value at the critical temperature found in the work of Vliegenthart and Lekkerkerker [J. Chem. Phys. 112, 5364 (2000)] is discussed in connection with the scale invariant mean-field approach proposed by Kulinskii and Bulavin [J. Chem. Phys. 133, 134101 (2010)]. We study the case of the Mie-class potentials, which is widely used in simulations of the phase equilibrium of the fluids. It is shown that due to the homogeneity property of the Mie-class potentials it is possible to connect the loci of the fluids with these model potentials in different dimensions.

摘要

讨论了 Vliegenthart 和 Lekkerkerker 在他们的工作[J. Chem. Phys. 112, 5364 (2000)]中发现的临界温度下第二维里系数值的 Vliegenthart-Lekkerkerker 关系与 Kulinskii 和 Bulavin 提出的标度不变平均场方法[J. Chem. Phys. 133, 134101 (2010)]之间的关系。我们研究了 Mie 类势的情况，该势在流体相平衡模拟中被广泛应用。结果表明，由于 Mie 类势的齐次性，有可能在不同维度上将具有这些模型势的流体轨迹连接起来。
