Liquids in contact with solids are submitted to intermolecular forces making liquids heterogeneous and, in a mechanical model, the stress tensor is not any more spherical as in homogeneous bulks. The aim of this article is to show that a square-gradient functional taking into account the volume liquid free energy corrected with two surface liquid density functionals is a mean field approximatio...

The generic square-gradient density-functional model with triple-parabolic free energy is used to study the stability of a cavity introduced into the stretched liquid. The various properties of the critical cavity, which is the largest stable cavity within the liquid, are compared with those of the critical bubble of the homogeneous bubble nucleation. It is found that the size of the critical c...

We evaluate the location of the gas-liquid coexistence line and of the associated critical point for the primitive model for water (PMW), introduced by Kolafa and Nezbeda [J. Kolafa and I. Nezbeda, Mol. Phys. 61, 161 (1987)]. Besides being a simple model for a molecular network forming liquid, the PMW is representative of patchy proteins and novel colloidal particles interacting with localized ...

Oxygen gas-liquid mass transfer coefficient was measured in a gas-induced pulsating flow bubble column. Pulsating amplitude had a great influence on kla under pulsating state of equal base flow and pulsating flow, which was enhanced up to 30 % compared with that under steady state; however, it had a negative effect on mass transfer under a fixed low base flow. It was also found that kla had a n...

Employing a time-dependent Ginzburg-Landau model, we investigate the phase ordering kinetics of nematic liquid crystals confined in a narrow pore. We consider various orientations of the surface field and compute domain growth laws and scaling functions. In the absence of any anchoring field we find that ~and in contrast to a confined binary liquid mixture! mere confinement of the liquid crysta...

As shown in the first part of our work [1], this paper deals with the presence of a three-phase regime (vapour-liquid-liquid) on the reactive distillation (RD) column stages due to a liquid liquid phase splitting (PHSP) between aqueous and organic phases. Special attention has to be paid on this subject, because detecting the three phase regime can lead to different operating and design strateg...

A comparative study is done of the propagation sound pulses in elongated Bose liquids and Bose-Einstein condensates Gross-Pitaevskii logarithmic models, by means Thomas-Fermi approximation. It shown that linear regime small density fluctuations essentially one-dimensional both direction perpendicular to cross section a liquid's lump. Under these approximations, it speed scales as square root pa...

Fermi liquid theory is the basic paradigm within which we understand the normal behavior of interacting electron systems, but quantitative values for the parameters that occur in this theory are currently unknown in many important cases. One such case is the two-dimensional homogeneous electron gas (2D HEG), which is realized in a wide variety of semiconductor devices. We have used quantum Mont...

This paper describes the viscosity variation of a liquid crystal under electric field, and its application to a controllable sliding bearing. Liquid crystal is known as a homogeneous organic liquid characterized by the long-range order of its molecular orientation. When an electric field is applied to a liquid crystal film as lubricant, the orientational order of molecules become parallel to th...
