  • Fortes, M. A.; Vaz, M. Fatima; Cox, Simon; Teixeira, Paulo (2007-11)
    We assess the stability of simple two-dimensional clusters of bubbles relative to small displacements of the vertices, at fixed bubble areas. The clusters analysed are: 1) flower clusters consisting of a central bubble of ...
  • Cox, Simon; Graner, François; Vaz, M. Fatima (2008)
    Using the Surface Evolver software, we perform numerical simulations of point-like deformations in a two-dimensional foam. We study perturbations which are infinitesimal or finite, isotropic or anisotropic, and we either ...
  • Weaire, Denis; Cox, Simon; Vaz, M. Fatima (2003)
    Experiments on a small cluster of bubbles in a nominally two-dimensional foam show an instability in which a topological change forces one of the bubbles to be ejected to the outside of the cluster at ap oint where this ...
