Evolution of the number of bubbles composing the foam as a function of the number of flips. Three surfactants are illustrated: PS, SLS, and SLES. The continuous curves are fits using Eq. (1).
Typical images of the foam after , 15, and 30 flips. Three surfactant molecules are illustrated: (a) PS, (b) SLS, and (c) SLES.
Probability distribution function of the number of bubble sides after , 15, and 30 flips in the case of SLES molecules. Solid curves are guides for the eyes using Gaussian fits, emphasizing mean values.
Second moment of the distribution of number of bubble sides as a function of the successive flips . Three surfactant molecules are illustrated.
Probability for finding two small bubbles of the same size apart from a distance . The size of the bubble is 20% of the mean bubble size.
Comparison between fitting parameters: (i) and for the foam evolution using Eq. (1), (ii) computed after 30 flips for the number of sides, and (iii) for the bubble size correlations. Error bars are indicated.
