Findings

Reduced surface tension maps onto a master curve.

A universal equation of state is derived for the Yukawa fluid.

Abstract

We have analyzed the currently available simulation results, as well as performed some additional Monte Carlo simulation for the hard-core attractive Yukawa fluid in order to study its corresponding state behavior. We show that the values of reduced surface tension map onto the master curve, and a universal equation of state can be obtained in the wide range of the attractive Yukawa tail length after a certain re-scaling of the number density. Some comparisons with other nonconformal potentials are presented and discussed.
