Candidates to the least perimeter partition of the surface of a sphere into N planar connected regions are calculated for N ≤ 32. A search procedure based upon random shuffling and combinatorial enumeration is used. It is ...

A programme of research is outlined which considers the foaming performance and foam behaviour of surfactant systems commonly encountered in hand-wash laundry detergent applications. An experimental study of the physical ...

We study the elasto-plastic behaviour of materials made of individual (discrete) objects, such as a liquid foam made of bubbles. The evolution of positions and mutual arrangements of individual objects is taken into account ...

The study of soap films spanning wire frames continues to provide insight into both static and dynamic properties of foams. Experiments show that sufficiently small triangular faces shrink spontaneously, with their area ...

We simulate quasistatic flows of an ideal two-dimensional monodisperse foam around different obstacles, both symmetric and asymmetric, in a channel. We record both pressure and network contributions to the drag and lift ...

A model is developed to describe the formation of metallic foams in which liquid drainage acts to collapse the foam before it can freeze. Numerical solution of the foam drainage equation, combined with the equations of ...

Two-dimensional bidisperse foams were simulated in cyclic, uniaxial, extensional shear. Mixing of bubbles of different sizes only occurs at high strains, and once mixed, the bubbles do not segregate. For liquid fractions ...

Bubble monolayers are widely used to probe the rheology of aqueous foams, and liquid content plays an important role in the response. We analyse the liquid distribution within three different types of two-dimensional foam, ...

Simulations of motion by mean curvature in bounded domains, with applications to bubble motionand grain growth, rely upon boundary conditions that are only approximately compatible with the equation of motion. Three closed ...

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 ...
