The transport properties of a fluid show a complex dependence with temperature and pressure due to the combination of different phenomena occurring at the microscopic scale. The entropy scaling concept aims at describing this complex behavior by expressing reduced transport properties as one-variable functions of the Tv-residual entropy, a thermody...

A new model for correlating self-diffusion coefficients is proposed here. It is based on the entropy scaling concept and makes it possible to quantitatively estimate self-diffusion coefficients in any fluid state (subcritical gas and liquid as well as supercritical states). A general relationship between a dimensionless form of the self-diffusion c...

Parameterization is defined as the method used to assign values to component-dependent parameters of an Equation of State (EoS). For SAFT-type EoS, historically, little attention has been paid to these methods, while higher importance was devoted to the theoretical foundations of the model. In this study, our ultimate objective was defined as the a...

Cubic equations of state have thus far yielded poor predictions of the thermodynamic properties of quantum fluids such as hydrogen, helium and deuterium at low temperatures. Furthermore, the shape of the optimal α functions of helium and hydrogen have been shown to not decay monotonically as for other fluids. In this work, we derive temperature-dep...

In the last two centuries, equations of state (EoS) have become a key tool for the correlation and prediction of thermodynamic properties of fluids. They can be applied not only to pure substances as well as to mixtures but they also constitute the heart of commercially available computer-aided-process-design software. In the last twenty years, tho...

This function contains two par...

The application of CO2 power cycles is advantageous to exploit high-temperature sources (500-800°C) in the case of available low-temperature heat sinks (15-25°C). However, their efficiency is strongly reduced for higher heat sink temperatures. At these temperatures, due to the low-critical temperature of CO2 (about 31°C), CO2 is in fact compressed...
