The Crystal Structure of Bubbles in the Wet Foam Limit
(2006)We have observed a rich variety of three-dimensional crystal and defect structures spontaneously formed by small (diameter 200 µm) bubbles in a wet foam. The observations confirm and extend those made by Bragg and Nye in ... -
The energy of fcc and hcp foams
(2020)We present Surface Evolver evaluations of the difference in energy between face-centred cubic (fcc) and hexagonal close-packed (hcp) foams in the usual idealized model, for liquid fractions ranging from the dry to the wet ... -
Models of wet two dimensional foams
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)In this thesis I used models and computer simulations to investigate the properties of two dimensional polydisperse foams from the dry limit of zero liquid fraction to the wet limit of 0.16 liquid fraction. Initially I ... -
Structures of columnar packings with soft and hard spheres
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)Columnar structures refer to dense cylindrical packings of spheres. They are ubiquitous throughout botany, foams, and have recently also become popular in nanoscience. We investigate such structures by carrying out computer ... -
Variation of average coordination number with liquid fraction for two-dimensional foams with finite contact angle
(2021)We present Surface Evolver computer simulations for two-dimensional (2d) foams in which the contact angle at which liquid films and Plateau borders meet is non-zero. We determine the average coordination number Z of bubbles ...
