Fluids inside a pore—an integral-equation approach

Abstract
Our study of fluids inside a pore, initiated in an earlier paper for slit and spherical pores, is continued here for cylindrical pores. We use an integral-equation approach, treating hard spheres and hard walls using both an Ornstein-Zernike and BBGKY formalism. In the former we use the Percus-Yevick (PY) closure for the bulk fluid and both the PY and hypernetted-chain (HNC) closures for the pore-particle closure. In the latter we use an appropriate form of a superposition approximation.
