Binary nucleation kinetics. 6. Partially miscible systems

We explore vapor-to-liquid phase transitions by numerically solving the birth-death equations for systems where the components are only partially miscible in the bulk liquid. In this case, multiple critical nuclei can coexist and the flux through two saddles contributes to particle formation. When there is a big difference between the monomer impingement rates, we often observe some of the flux crossing the ridge between the two saddles. Despite these complications, the difference between the numerical nucleation rates and the appropriate analytical rate expressions is usually less than 35%.
