Persistence Measures
Soap froths as typical disordered two-dimensional cellular structures, exhibiting spatial and temporal evolution, have been studied. Direct computer simulation studies, of initial froth structures, based both on a regular geometry with defect and on random Voronoi constructions are considered. Differences in the transient behavior are discussed. In particular, the scaling properties and virtual phase dynamics are compared with shell structure theory. It appears that defect location and pattern of cell inclusion in the virtual phase causes considerable variation in the froth evolutionary behavior, despite the limitation of a system size. Distinctive patterns of response can be identified for the different froth regions.
