Equations of state for fluids containing alternating heteronuclear chain molecules

摘要

Statistical associating fluid theory-dimer (SAFT-D) and monomer-dimer mixture theory equations of state of linear homonuclear chain are extended to fluids containing alternating heteronuclear chain molecules separately. The proposed models account for the appropriate site-site correlation functions at contact. The modified equations of state show a good agreement with generalized Flory dimer theory and MD simulation data for small and medium size ratio of hard sphere diameters. (C) 2003 Elsevier B.V.
