Abstract
We present a simple but accurate equation of state for double Yukawa fluids based on the
variational series mean spherical approximation (VSMSA). This allows us to investigate the
vapour–liquid equilibrium and its related thermodynamic properties. The comparisons with
computer simulation results of the Lennard–Jones (LJ) potential suggest the importance of
treating the attractive tail of the potential accurately via VSMSA. The estimated reduced
critical parameters TC= 1.342, ρ C= 0.29 and PC= 0.135 are in good agreement with other ...
