– A mean-field theory for the geometry and diffusive growth rate of soap bubbles in dry 3D foams is presented. Idealized foam cells called isotropic Plateau polyhedra (IPPs), with F identical spherical-cap faces, are introduced. The geometric properties (e.g., surface area S, curvature R, edge length L, volume V ) and growth rate G of the cells are obtained as analytical functions of F , the sole variable. IPPs accurately represent average foam bubble geometry for arbitrary F ≥ 4, even though… CONTINUE READING
