    Wall slip in the molecular dynamics simulation of thin films of hexadecane (1999)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 110 (1999), S. 2612-2620

    Notes: A molecular dynamics simulation of a thin liquid film as it is sheared between two planar walls is reported. The model liquid is composed of linear chain molecules of hexadecane (C16H34) with intramolecular architecture such as bond stretching, angle bending and dihedral potentials included in the model. Designing a model that can mimic the planar shear flow enables us to study important questions on the effects of the wall properties on the slip between the liquid film and the wall. Different properties of the wall such as wall density, wall stiffness and wall–fluid interaction strength have been studied to determine the slip between the wall and fluid. The slip has been investigated for strong and weak adsorbing surfaces at various shear rates. The results emphasize the importance of adsorption on the degree of slip. The dependence of slip on the film thickness is also demonstrated. © 1999 American Institute of Physics.

    The separation of viscous jets (1985)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 28 (1985), S. 23-25 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A viscous jet is not usually observed to separate from a sharp edge in the manner expected theoretically. In the present paper the separation of a creeping jet emerging from a tube with a rounded exit is considered. As a separation criterion, in the absence of surface tension, we propose that the traction normal to the nozzle surface drops to zero at the separation point. Boundary-element calculations then show a behavior that agrees with experimental data and with previous finite-element computations. They also permit the Michael condition to be observed at separation, so that the discrepancy between finite-element calculations and theory is removed.

    Description / Table of Contents: Zusammenfassung Dieser Arbeit liegt eine eingehende theoretische Untersuchung eines Grenzfalles der Spiralströmung einerOldroyd-Flüssigkeit zugrunde. Die Bearbeitung geschieht hauptsächlich auf graphische Weise. Eine Diskussion der Resultate dieser Untersuchung ist bis zum Erhalt eines Vergleiches über das Verhalten einer wirklichen Polymerlösung (Teil II) aufgeschoben.
    Notes: Abstract A detailed theoretical investigation of a limiting case of helical flow for anOldroyd liquid is presented, largely in graphical form. Discussion of results is deferred until comparison with the flow of real polymer solutions (Part II), has been made.

    Description / Table of Contents: Zusammenfassung In dieser Arbeit wird eine spiralförmige Strömung, die sich aus einerCouette- und einerPoiseuilleschen Kanalströmung zusammengesetzt denken läßt, benützt, um die Gültigkeit derOldroydschen Gleichungen für die Strömung wirklicher Polymere zu untersuchen. Der erste Teil dieser Arbeit umfaßt die theoretische Untersuchung, obwohl einige experimentelle Ergebnisse auch hier behandelt werden. Solche Ergebnisse beziehen sich auf Untersuchungen mit Polymethyl-Methacrylat in Toluollösungen. Es wird gezeigt, daß gute Übereinstimmung zwischen Theorie und Experiment besteht, wenn das Verhältnis der augenscheinlichen Viskosität (bei Schergeschwindigkeit Null) zur Viskosität (bei großer Schergeschwindigkeit) kleiner als 6 ist. Für höhere Werte dieses Verhältnisses wird die abgeleitete Grundgleichung zu ungenau und muß daher geändert werden. Eine erweiterte Form wird vorgeschlagen.
    Notes: Abstract Helical flow, consisting of superposed shear and channel flow, is used to evaluate the relevance ofOldroyd's theoretical equation of state to the flow of real polymer solutions. A theoretical solution has been given (Part I) and some experiments (mainly with polymethyl-methacrylate in toluene solutions) are described here. It is shown that agreement between theory and experiment is fair when the ratio (apparent viscosity at zero shear rate)/(apparent viscosity of large shear rate) is less than about 6. For higher ratios the equation is inapplicable unless modified, and an alternative form is suggested.
