non-uniform fluids. In particular, for a three-phase line of contact, they showed that the translation invariance of the … variational integral for the excess free energy implies a balance of forces at the three-phase line. In this paper we consider the …

Fluctuations in the structure of three-phase lines

Bukman, Dirk Jan; Widom, B - In: Physica A: Statistical Mechanics and its Applications 251 (1998) 1, pp. 27-39

We study the fluctuations in the density and composition of the contact line at which three phases meet. The equilibrium structure of the contact line is obtained by minimizing a model free-energy functional and then the fluctuations about that structure are analyzed via the spectrum of the free...

The Maxwell–Stefan equations for diffusion in multiphase systems with intersecting dividing surfaces

Sagis, Leonard M.C. - In: Physica A: Statistical Mechanics and its Applications 254 (1998) 3, pp. 365-376

In this paper, the Maxwell–Stefan theory for diffusion is extended to multiphase systems with intersecting dividing surfaces. The general Maxwell–Stefan equation is separated into equations for bulk diffusion, surface diffusion and (common) line diffusion. Expressions for the driving forces...
