Resumen:
Multilayer approximation for a confined fluid in a slit pore
Abstract
A simple Lennard-Jones fluid confined in a slit nanopore with hard walls is studied on
the basis of a multilayer structured model. Each layer is homogeneous and parallel to
the walls of the pore. The free energy of this system is constructed following van der
Waals-like approximations, with the advantage that the model geometry permits to
obtain analytical expressions for the involved integrals. Being the multilayer in
thermodynamic equilibrium, a system of non linear equations is obtained for the
densities and widths of the layers. Numerical solution of the equations gives the density
profile and the longitudinal pressures. The results are compared with Monte Carlo
simulations.
