abstract = {The surface tensions of pure refrigerants were predicted using a density gradient theory (DGT) coupled with a perturbed hard-sphere equation of state (EoS) approach. The EoS is taken from the Carnahan â€“Starling hard-sphere equation with the perturbation term of Dohm-Prausnitz (CS-DP EoS), in which the relevant parameters to the molecular size and energies are universal functions of temperature in describing the equilibrium bulk properties. Then DGT+CS-DP EoS model has been employed for predicting the surface tension of 26 pure refrigerants taken from a Chemistry Webbook provided by NIST. Our calculations on the surface tension data from the DGT+CS-DP model led to an average absolute deviation of 4.84%. Then, the degree of accuracy of DGT+CS-DP model has also been compared with other DGT-based model.},
