Peng-Robinson perturbation theory

As was pointed out earlier, the gradient theory can be linked easily to a semi-empirical equation of state. The equations of state applied in this study are the Peng-Robinson equation of state and the Associated-Perturbed-Anisotropic-Chain-Theory (APACT). The only effect on the interfacial tensions of pure fluids that is strongly influenced by the selected equation of state is the behavioitr in the near-critical region, since other differences are completely annulled by the fitting procerdure that is applied for the influence parameter. [Pg.207]
