    The relation between dynamics of wetting and nonwetting liquids (2001)

    Notes: The dynamics of wetting liquids has been related to the dynamics of nonwetting liquids. It appears that the response of wetting liquids form an envelop to the family of responses for liquids with nonzero contact angles. These are singular solutions, and the mathematics of singular solutions has been used to obtain results for the generally less accessible case of wetting liquids from the more accessible nonwetting liquids. Three cases have been analyzed. In the first, the well known Voinov–Hoffman–Tanner rule is derived for a spreading drop of a wetting liquid starting with a known expression for the nonwetting case. In the second, the theoretical results for the blow-off experiments for the nonwetting case have been used to obtain the results for the wetting case, allowing a successful comparison between the theory and experiments. In the third, the solution for drop spreading by Hocking and Rivers [J. Fluid Mech. 121, 425 (1982)] for nonwetting liquids where the lubrication theory approximation is not valid is used to derive the solution for the wetting. The present work appears to be the first in determining the connection between the dynamics of wetting and nonwetting liquids of any kind. © 2001 American Institute of Physics.

    The absence of a rheological effect on the spreading of small drops (2001)

    Notes: The fluid mechanics of the movement of the contact line region for non-Newtonian fluids has been analyzed using the method of Joanny and de Gennes [C. R. Acad. Sci., Ser. II: Mec., Phys., Chim., Sci. Univers Terre 299, 279 (1984)] where under lubrication theory approximation the rate of viscous dissipation is equated to the rate of surface work to get the expression for the rate of spreading. Two kinds of fluids are considered, one where the viscosity is dependent on shear rate but there are no normal stresses, and another where there are normal stresses but the coefficients are not dependent on the shear rate. Both show the spreading rates to be independent of the non-Newtonian nature of the fluids to a good approximation, with the zero shear viscosity replacing the Newtonian viscosity in the result of Joanny and de Gennes. This appears to be in keeping with the available experimental data. © 2001 American Institute of Physics.

    Diffusion in inhomogeneous polymer membranes (1995)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 103 (1995), S. 7114-7119

    Notes: The dual mode sorption solubility isotherms assume, and in instances Zimm–Lundberg analysis of the solubilities show, that glassy polymers are heterogeneous and that the distribution of the solute in the polymer is also inhomogeneous. Under some conditions, the heterogeneities cannot be represented as holes. A mathematical model describing diffusion in inhomogeneous polymer membranes is presented using Cahn and Hilliard's gradient theory. The fractional mass uptake is found to be proportional to the fourth root of time rather than the square root, predicted by Fickian diffusion. This type of diffusion is classified as pseudo-Fickian. The model is compared with one experimental result available. A negative value of the persistence factor is obtained and the results are interpreted. © 1995 American Institute of Physics.

    Dynamics of an adsorbed patch and a model for spreading of films of ultralow thicknesses (1996)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 105 (1996), S. 8909-8913

    Notes: The dynamics of ultrathin films of liquids with vanishing 3D volatility, on solid surfaces, has been modeled by assuming that the films can be taken to be adsorbed patches spreading under surface diffusion. When the phase behavior of the adsorbed films is taken into account, it is seen that a vapor patch will spread without limits and evolve into a Gaussian profile. For a liquid film which has low 2D volatility, a patch will appear to equilibrate and the surface ahead will remain dry. This is the "pancake,'' a case where a wetting liquid stops spreading. The spreading kinetics is generally seen to be the usual square-root-of-time type, although exceptions are also seen. A simple case of non-Fickian diffusion has been included, but fails to give anticipated results at least in a simple model. © 1996 American Institute of Physics.
