Structure of random foam

Kraynik, Andrew M.; Reinelt, Douglas A.; Van Swol, Frank

The equilibrium microstructure of dry soap foams was computed using the Surface Evolver. Foam polydispersity was characterize using a novel parameter based on the surface-volume mean bubble radius R32. The dry foam limit where liquid volume fraction was negligible was considered. The cells were trivalent polyhedra, the faces were surfaces of constant mean curvature that meet at dihedral angles of 120° and the cell edges meet at the tetrahedral angle across ≅ 109.47 °.
