Resumen:

The interfacial properties of short-range square well fluid with λ=1.15, 1.25, and 1.375 were determined by using single canonical Monte Carlo simulations. Simulations were carried out in the vapor-liquid region. The coexistence curves of these models were calculated and compared to those previously reported in the literature and good agreement was found among them. We found that the surface tension curves for any potential model of short range form a single master curve when we plot γ^* vs T/T_c. It is demonstrated that the critical reduced second virial coefficient B₂^* as a function of interaction range or T_c^* is not constant. [ABSTRACT FROM AUTHOR]
