Summary: Interfacial properties, such as interfacial mass transfer, play a crucial role in the design and optimization of industrial separation processes. This study investigates the interfacial behavior of two quaternary systems and the relationship between interfacial enrichment and mass transfer. By combining the Concentration Gradient Theory (CGT) with the Koningsveld-Kleintjens (KK) model, the interfacial tension and interfacial concentration profiles are calculated. The results show that interfacial mass transfer in quaternary systems can be accurately modeled by adjusting a single additional binary mobility coefficient, and indicate a potential link between interfacial enrichment and interfacial mass transfer.

Interfacial properties of fluorinated (F)-gases in azeotropic condition

Bastian Gonzalez-Barramuno et al.

Summary: In this study, molecular dynamic simulations and density gradient theory combined with statistical associating fluid theory were used to model and understand the interfacial behavior of azeotropic refrigerant mixtures. The results show that despite the non-ideal behavior in these mixtures, the models are able to accurately reproduce the changes in interfacial behavior.

The Intrinsic Fragility of the Liquid-Vapor Interface: A StressNetwork Perspective

Muhammad Rizwanur Rahman et al.

Summary: This study investigated the evolution of the liquid-vapor interface of a Lennard-Jones fluid using molecular dynamics simulations with the intrinsic sampling method. The results showed a clear damping of intrinsic profiles with increasing temperature, and a linear variation of stress clusters' space-filling nature with increasing surface tension or decreasing temperature, indicating more disjointed stress fields at higher temperatures resulting in fragile interfaces and reduced surface tension.

Interfacial properties of binary azeotropic mixtures of simple fluids: Molecular dynamics simulation and density gradient theory

Jens Staubach et al.

Summary: This study investigates the interfacial properties of binary azeotropic mixtures of Lennard-Jones truncated and shifted fluids using molecular dynamics simulation and density gradient theory. The results show that the type of azeotropic behavior varies with different mixtures, and there is a close relationship between the interfacial properties and the phase behavior.

Mass transfer through vapour-liquid interfaces: a molecular dynamics simulation study

Simon Stephan et al.

Summary: A quasi-stationary molecular dynamics simulation method based on the dual control volume (DCV) method is described for studying mass transfer through vapour-liquid interfaces. By prescribing the chemical potential in control volumes in the vapour domains, mass flux is generated, leading to significant differences in the mass flux of the low-boiling component in two binary Lennard-Jones mixtures, despite similar bulk diffusion coefficients and prescribed chemical potential differences.

Effects of molecular shape on alcohol aggregation and water hydrogen bond network behavior in butanol isomer solutions

Seungeui Choi et al.

Summary: The four butanol isomers, n-butanol, sec-butanol, isobutanol, and tert-butanol, exhibit different aggregation behaviors in water solutions due to their molecular shapes, affecting the water H-bond network structure and phase diagram. Tert-butanol forms small aggregates while the other three isomers form chain-like alcohol aggregates in concentrated solutions. Graph theoretical analysis reveals that tert-butanol aggregates have a different morphological structure from the other three isomers and impact water structure significantly, leading to a homogeneous solution formation.
