Adaptation of the Z-cone model to the estimation of the energy of a bcc foam
HUTZLER, STEFAN; WEAIRE, DENIS (2015) -
Analysis of liquid metal foams through X-ray radioscopy and microgravity experiments
HUTZLER, STEFAN (2014)Complex liquid structures such as metallic foams were produced in a furnace that allowed in situ X-ray monitoring of the evolution of the structure and distribution of the liquid in the foam. The experiments were carried ... -
Applications and extensions of the Z-cone model for the energy of a foam
WEAIRE, DENIS; HUTZLER, STEFAN (2015)We present an extended analysis of the Z -cone model for the estimation of the energy of an ordered foam. In particular, we show that it results in an interaction potential with an expone ... -
Bubble-bubble interactions in a 2D foam, close to the wet limit
HUTZLER, STEFAN; WEAIRE, DENIS (2017) -
Chapter 16: The structure of liquid foams
HUTZLER, STEFAN (CRC Press, 2018) -
The continuum theory of shear localization in two-dimensional foam
HUTZLER, STEFAN; WEAIRE, DENIS (2010)We review some recent advances in the rheology of two-dimensional liquid foams, which should have implications for three-dimensional foams, as well as other mechanical systems that have a yield stress. We focus primarily ... -
Convective instability in foam drainage
WEAIRE, DENIS LAWRENCE; HUTZLER, STEFAN (EDP Sciences, 1998)The use of a column of steadily drained foam as a sample of wet foam is limited by flow instability as the liquid fraction is increased. We report a study of this instability, which takes the form of a convective roll ... -
The Crystal Structure of Bubbles in the Wet Foam Limit (Amendment)
WEAIRE, DENIS LAWRENCE; HUTZLER, STEFAN (Royal Society of Chemistry, 2006)We have observed a rich variety of three-dimensional crystal and defect structures spontaneously formed by small (diameter 200 mm) bubbles in a wet foam. The observations confirm and extend those made by Bragg and Nye ... -
Dense packings of spheres in cylinders: Simulations
CHAN, HO-KEI; HUTZLER, STEFAN; WEAIRE, DENIS (2012)We study the optimal packing of hard spheres in an infinitely long cylinder, using simulated annealing, and compare our results with the analogous problem of packing disks on the unrolled surface of a cylinder. The densest ... -
Dynamics of a flexible fibre in a sheared two-dimensional foam: numerical simulations
HUTZLER, STEFAN (2017) -
Experimental observation of scaling laws for alternating current and direct current conductivity in polymer-carbon nanotube composite thin films
HUTZLER, STEFAN; BLAU, WERNER; COLEMAN, JONATHAN; DRURY, ANNA (2002)Alternating current (ac) and direct current (dc) conductivities have been measured in polymer-nanotube composite thin films. This was carried out for a range of concentrations of multiwall nanotubes in two polymer hosts, ... -
An experimental realisation of the Weaire-Phelan structure in monodisperse liquid foam
HUTZLER, STEFAN; WEAIRE, DENIS (2012)The Weaire-Phelan (WP) structure is the lowest energy structure known of an ideal monodisperse foam in the dry limit. To date, it has not been realized in the laboratory. Instead Lord Kelvin's 1887 structure, which it ... -
An experimental study of columnar crystals using monodisperse microbubbles,
HUTZLER, STEFAN (2015) -
Foam as a complex system
WEAIRE, DENIS; HUTZLER, STEFAN (2009)What is a `complex system?? The two-dimensional foam, as originally popularized by Cyril Stanley Smith, provides an ideal context in which to explore this question. -
Ideal wet two-dimensional foams and emulsions with finite contact angle
HUTZLER, STEFAN; WEAIRE, DENIS (2018) -
Interactions of fibres with simple arrangements of soap films
HUTZLER, STEFAN (2017) -
Measurement of Foam Density Profiles Using AC Capacitance
WEAIRE, DENIS LAWRENCE; HUTZLER, STEFAN (EDP Sciences, 1995)The dynamics of foam drainage (free, forced and pulsed) is monitored by the determination of local liquid density using a vertical array of capacitors. Liquid profiles are obtained for various drainage experiments. The ... -
The mechanics of liquid foams: history and new developments
WEAIRE, DENIS; HUTZLER, STEFAN (2011)The story of some recent developments in foam rheology is related at key points to the remarkable early contributions of Henry Princen, who pioneered the rigorous modern development of the subject. His general approach of ... -
Observations of a variety of drainage patterns in bamboo foams
WEAIRE, DENIS LAWRENCE; HUTZLER, STEFAN (EDP Sciences, 2008)We have explored the patterns of drainage in a bamboo foam, i.e. a foam consisting of an arrangement of parallel soap films with equidistant spacing. We find an intriguing variety of such patterns, both static and dynamic. ... -
Onset of rigidity for stretched string networks
HUTZLER, STEFAN; WEAIRE, DENIS LAWRENCE (Institute of Physics, 2005)We define and analyse an elementary model for a network of strings with random natural lengths. As this system is expanded, a threshold is reached where some of the strings form a taut string network. Further expansion ...
