EDGE SCALING OF SOAP FROTH

We investigate the scaling properties of the edge distribution of soap froth and compare it with the area scaling law. The data collapse for edge scaling of cells belonging to the same topological class is expl ained by a harmonic expansion of the energy of the froth with area-per imeter constraint. The edge-scaling hypothesis is found to be comparab le to area scaling. The implication on existing theories for the evolu tion of soap froth is discussed. (C) 1998 Elsevier Science B.V.
