  • Rheological properties of the soft disk model of 2D foams 

    HUTZLER, STEFAN; WEAIRE, DENIS LAWRENCE (American Physical Society, 2008)
    The soft-disk model previously developed and applied by Durian D. J. Durian, Phys. Rev. Lett. 75, 4780 1995 is brought to bear on problems of foam rheology of longstanding and current interest, using twodimensional systems. ...
  • Steady-State Drainage of an Aqueous Foam 

    WEAIRE, DENIS LAWRENCE; HUTZLER, STEFAN (American Physical Society, 1993)
    The process of wetting of a monodisperse foam by the continuous addition of liquid from the top has been investigated for a cylindrical column. The velocity of the interface between dry and wet foam was found to vary as ...
  • Theory of diffusivelight scattering from disordered materials 

    WEAIRE, DENIS LAWRENCE; LUNNEY, JAMES GERARD; HUTZLER, STEFAN (International Society for Optical Engineering, 1994)
    It is suggested that the measurement of the angular distribution of light transmitted through a thick slab of diffusively scattering material may provide information about the nature of the local scattering events. Monte ...
  • Time for a rethink of research proposal evaluation? 

    WEAIRE, DENIS LAWRENCE (2007)
    The processes of research proposals and evaluation have become ever more elaborate, but the system remains primitive. This paper argues for a fresh look at existing practices, with a view to developing less onerous and ...
  • Torque in nested Halbach cylinders 

    WEAIRE, DENIS LAWRENCE; COEY, JOHN MICHAEL DAVID (IEEE, 1999)
    Permanent magnet variable flux sources are produced by rotating two nested N-segment, permanent magnet, Halbach cylinders. Torque is primarily an end effect, determined by field non-uniformities due to the fmite length ...
  • Torque in nested Halbach cylinders 

    Ni Mhiochain, T.R; WEAIRE, DENIS LAWRENCE; MCMURRY, SARA; COEY, JOHN MICHAEL DAVID (IEEE, 1999)
  • Torque in nested Halbach cylinders 

    Ni Mhiochain, T.R.; WEAIRE, DENIS LAWRENCE; MCMURRY, SARA; COEY, JOHN MICHAEL DAVID (IEEE, 1999)
  • Toying with physics 

    HUTZLER, STEFAN; WEAIRE, DENIS LAWRENCE (European Physical Society, 2007)
    In the early 19th century the popularisation of science became a vogue, expressed in books that often took the form of ?conversations on natural philosophy?. They may have echoed the discourse of the classical dialogue ...
  • Two-dimensional foam rheology with viscous drag 

    WEAIRE, DENIS LAWRENCE; HUTZLER, STEFAN (American Physical Society, 2006)
    We formulate and apply a continuum model that incorporates elasticity, yield stress, plasticity, and viscous drag. It is motivated by the two-dimensional foam rheology experiments of Debregeas et al. [Phys. Rev. Lett. ...
  • The two-dimensional viscous froth model for foam dynamics 

    WEAIRE, DENIS LAWRENCE; HUTZLER, STEFAN (American Physical Society, 2004)
    The two-dimensional viscous froth model is a simple tractable model for foam rheology and coarsening. It includes, but is not confined to, the quasistatic regime. Here we present a detailed analysis and implementation of ...
  • Wall slip of bubbles in foams 

    WEAIRE, DENIS LAWRENCE (American Institute of Physics, 2006)
    We present a computational analysis of the flow of liquid foam along a smooth wall, as encountered in the transport of foams in vessels and pipes. We concentrate on the slip of the bubbles at the wall and present some ...
