“…This method is very successful at correlating the surface tension for classical pure nonassociated fluids ranging from argon to hexafluorobenzene. 10 It is interesting to ask whether this same relationship holds for quantum fluids as well. We have therefore used Faizullin's method to correlate the experimentally measured values of surface ten- sion for H 2 and D 2 .…”

“…Theoretical and empirical methods have been used to calculate surface tension since the 1920s. [1][2][3][4][5][6][7][8][9][10] Some of the more modern methods are able to predict the surface tension of classical fluids with an error of less than 5% compared to experimental data. 6 Similar methods have been suggested for quantum fluids, 4,11-13 but they are either dependent on the parameters fitted from experimental data or not capable of quantitatively predicting the surface tension of quantum fluids.…”

We present the first molecular simulations of the vapor-liquid surface tension of quantum liquids. The path integral formalism of Feynman was used to account for the quantum mechanical behavior of both the liquid and the vapor. A replica-data parallel algorithm was implemented to achieve good parallel performance of the simulation code on at least 32 processors. We have computed the surface tension and the vapor-liquid phase diagram of pure hydrogen over the temperature range 18-30 K and pure deuterium from 19 to 34 K. The simulation results for surface tension and vapor-liquid orthobaric densities are in very good agreement with experimental data. We have computed the interfacial properties of hydrogen-deuterium mixtures over the entire concentration range at 20.4 and 24 K. The calculated equilibrium compositions of the mixtures are in excellent agreement with experimental data. The computed mixture surface tension shows negative deviations from ideal solution behavior, in agreement with experimental data and predictions from Prigogine's theory. The magnitude of the deviations at 20.4 K are substantially larger from simulations and from theory than from experiments. We conclude that the experimentally measured mixture surface tension values are systematically too high. Analysis of the concentration profiles in the interfacial region shows that the nonideal behavior can be described entirely by segregation of H(2) to the interface, indicating that H(2) acts as a surfactant in H(2)-D(2) mixtures.

“…The enthalpy of vaporization has already been correlated with many physical properties, such as relationships involving liquid volume on the saturation line [29], and surface tension [30]. Informative and exhaustive reviews of the theoretical as well as experimental developments in this area are available in the literature [8,[31][32][33][34].…”

According to phenomenological scaling and the law of corresponding states, reduced coordinates F * -T * , where F * represents the reduced thermodynamic properties (enthalpy of vaporization, speed of sound, surface tension, saturated liquid density) and T * is the reduced temperature, are introduced for the prediction of the thermodynamic properties of alkali metals. Values of the thermodynamic properties from the melting point up to boiling point are correlated. It has been shown that the correlation between reduced thermodynamic properties, as well as with the reduced temperature, can be expressed as a unique straight-line plot with a linear correlation coefficient of 0.9998. The proposed correlation has a simple form for easy calculation, requires only the melting and boiling point parameters, which are usually easy to acquire, and can predict the thermodynamic properties from the melting temperature up to the boiling temperature accurately.
