The structure of fluids confined by planar walls is studied using density functional theory. The density functional used is a generalized form of the hypernetted chain (HNC) functional which contains a term third order in the density. This term is chosen to ensure that the modified density functional gives the correct bulk pressure. The proposed density functional applied to a Lennard-Jones...

When a fluid is confined to a nanopore, its thermodynamic properties differ from the properties of a bulk fluid, so measuring such properties of the confined fluid can provide information about the pore sizes. Here, we report a simple relation between the pore size and isothermal compressibility of argon confined in such pores. Compressibility is calculated from the fluctuations of the number o...

In this work, we combine our earlier proposed empirical potential based quasi-continuum theory, (EQT) [A. V. Raghunathan, J. H. Park, and N. R. Aluru, J. Chem. Phys. 127, 174701 (2007)], which is a coarse-grained multiscale framework to predict the static structure of confined fluids, with a phenomenological Langevin equation to simulate the dynamics of confined fluids in thermal equilibrium. A...

This study uses nonequilibrium molecular dynamics simulation to explore the rheology of confined liquid alkanes. Two alkanes that differ in molecular structural complexity are examined: tetracosane (C24H50!, which is a linear alkane, and squalane (C30H62!, which has six symmetrically placed methyl branches along a 24 carbon backbone. These model lubricants are confined between model walls that ...

The melting transition of bulk and confined Stockmayer fluids (μ = 1) is analyzed using molecular dynamic simulations. The solid−liquid coexistence temperature is evaluated using a modified three-stage pseudosupercritical transformation path. The bulk melting temperature calculated using the aforementioned method agrees well with the literature value. Melting temperatures of the Stockmayer flui...
