    Binary homogeneous nucleation theory for the gas–liquid transition: A nonclassical approach (1991)

    Notes: We have employed density functional theory to study gas–liquid nucleation in binary fluids. Effects of surface enrichment and curvature are naturally included in this novel statistical mechanical approach, allowing the classical capillarity approximation to be tested. In this paper we apply the theory to mixtures of Lennard-Jones fluids (modeled on argon and krypton). For these nearly ideal mixtures, the magnitude of nonclassical effects tend to be small, but systematic deviations do appear, with the ratio of the classical to nonclassical rate showing a maximum at intermediate compositions.

    Nucleation in dipolar fluids: Stockmayer fluids (1993)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 99 (1993), S. 4670-4679

    Notes: We have used density functional theory to begin the study of nucleation in dipolar fluids. The simplest case of a system composed of Stockmayer molecules has been considered. Under a Weeks–Chandler–Andersen perturbation scheme we obtain the corresponding bulk phase diagram and interfacial properties of planar and spherical liquid–vapor interfaces. Molecules tend to align perpendicular to the interface on the liquid side of small droplets, but the overall effect of this on free energies is negligible. The resulting nonclassical effects on nucleation rates are, hence, close to those found in nonpolar Lennard-Jones fluids.

    Thermal nucleation and cavitation in helium-3 fluids (1996)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 104 (1996), S. 3726-3731

    Notes: We have investigated droplet nucleation and bubble cavitation in the quantum fluid helium-3 based on a nonlocal density-functional approach. A marked effect of droplet (or bubble) curvature on the rate of droplet nucleation or cavitation has been found. Without considering this curvature effect (as in the classical theory of nucleation) the droplet nucleation rate for helium-3 could be underestimated (i.e., near 1 K) or overestimated (i.e., near 2.5 K) by orders of magnitude, respectively; for bubble cavitation, the rate could be underestimated by more than twenty orders of magnitude (near 1 K). © 1996 American Institute of Physics.
