Dynamic surface tension and classical nucleation theory

摘要

Regular solution theory is used to develop the concentration dependence for both the equilibrium and dynamic surface tension of waterndash;alcohol binary solutions. The equilibrium surface tensions of methanolndash;water, ethanolndash;water, andnhyphen;propanolndash;water binary solutions are used to fit the parameters of the theory and the dynamic surface tension is calculated. The dynamic surface tension compares favorably with the surface tension which fits classical nucleation theory vs composition at a nucleation rate of one nuclei per cubic centimeter per second.
