Surface tension and vapour-liquid phase coexistence of variable-range hard-core attractive Yukawa fluids

摘要

The vapour-liquid phase coexistence and surface tension of hard-core Yukawa fluids with short attraction range, lambda = 8.0, 9.0 and 10.0, are reported using grand-canonical transition-matrix Monte Carlo (GC-TMMC) with the histogram reweighting method. Surface tension is calculated using finite-size scaling approach of Binder. We also compare GC-TMMC results with the available literature data for Yukawa fluids with lambda = 1.8, 3.0 and 4.0. Critical properties obtained from rectilinear diameter approach and least square-technique are also reported. GC-TMMC results are found to be more precise than the previous reported values. We also present the corresponding state of surface tension for extremely short-range attractive Yukawa fluids.
