Liquid–liquid interfaces and nucleation in partially miscible Lennard–Jones ~LJ! mixtures are considered using density functional theory. We present phase diagrams, interfacial liquid–vapor and liquid–liquid profiles, and gas–liquid as well as liquid–liquid surface tensions for two types of mixtures having different mixing rules for the LJ energy parameter. A simple local density approximation ...

In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...

in this paper the density and temperature dependencies of surface tension are investigated. using the lennard-jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and chlorofluorocarbons (cfcs) fluids, where  is surface tension and r = 1/v is molar density. the linearity behavior of the derived equation is wel...

the presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. the aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coefficie...

in this article, the crystallization of polyethylene is investigated by the modified weighted density approximation. also, a direct correlation function of polyethylene based on the rism theory is used. the free energy of a polyethylene is calculated using the density functional theory. the crystallization and also the solid and liquid densities of polyethylene are calculated and compared with ...
