(722f) Surface Tension Models for Industrial Applications

Surface tension and related properties determine the value and performance of many chemical formulations. The modeling of surface tension is essential to the establishment of structure-property relationship, calculations of chemical processes and modeling of other processes where surface tension is important (reservoir simulation and enhanced oil recovery), etc. Despite its simple definition, accurate modeling of surface tension can be challenging, especially for highly nonideal systems in which surface concentrations depart greatly from bulk values. In this work, we review a broad range of surface tension models, from empirical models to molecular theories and simulations. The advantages and disadvantages of these approaches are illustrated through comparisons with experimental data. Our recommendations for future improvements are also discussed.
