Surface Tension
Below the available surface tension models are presented.
Gas-Liquid Surface Tension
Ideal
The gas-liquid surface tension is predicted by ideally mixing the pure species correlations. It is independent of pressure, vapor temperature or composition.
(2-261)
where the vapor-liquid surface tension correlations, σi,vl, must be specified for all species i, and are evaluated at the temperature of the liquid phase.
Winterfeld
Following Winterfeld (Ref. 78), the vapor-liquid surface tension is predicted by mixing the pure species correlations according to
(2-262)
It is independent of pressure, vapor temperature and composition. The vapor-liquid surface tension correlations and liquid density correlations must be specified for all species i, and are evaluated at the temperature of the liquid phase.
