An experimental realisation of the Weaire-Phelan structure in monodisperse liquid foam
The Weaire-Phelan (WP) structure is the lowest energy structure known of an ideal monodisperse foam in the dry limit. Up to now it has not been realised in the laboratory. Instead Lord Kelvin’s 1887 structure, which it supplanted in 1994, has repeatedly been found in attempts to produce an ordered structure. This paradox is attributable to the flat walls of the containers used, with which the K...
متن کاملComputation of Equilibrium Foam Structures Using the Surface Evolver
Weaire was supported in part by the EC Science Programme, contract SC*-CT92-0777 and HCM Network Contract ERBCHRX940542. Phelan was supported in part by Shell Research (Amsterdam) and an Irish-American Partnership studentship. The Surface Evolver has been used to minimise the surface area of various ordered structures for monodisperse foam. Additional features have enabled its application to fo...
متن کاملFoam microrheology: from honeycombs to random foams
Foam includes a broad range of materials from shaving cream to the flexible polyurethane that cushions our seats. This overview covers two decades of research on the rheology of liquid foam from a micromechanical point of view. These highly structured, multiphase fluids exhibit rich rheological response that can be related to geometry and mechanics at the cell level. Properties of interest incl...
متن کاملComparing the Weaire-phelan Equal-volume Foam to Kelvin’s Foam
The problem of partitioning space into equal-volume cells, using the least interface area, was considered in 1887 by Sir William Thomson, Lord Kelvin [Kel]. His proposed solution yields a foam with cells of a single shape, tiling space by the translations of the body-centered cubic lattice. In 1993, Denis Weaire and Robert Phelan [WP] proposed a new equal-volume foam with two different cell sha...
متن کاملThe rheology of two-dimensional foams
Why study the rheology of foams? The motivations are widespread and diverse (Weaire and Hutzler 1999). Foams are common in oil extraction and industrial cleaning. Closer to home, an understanding of flowing foams helps to extinguish fires more efficiently and to generate the perfect pint of beer. At low shear-rates a foam behaves as an elastic solid, while at high shearrates it yields like a li...
