Experimental link of coarsening rate and volume distribution in dry foam

International audienceIn dry foam, we investigate the link between coarsening rate and bubble distribution. Revisiting Mullins' predictions (Mullins W. W., J. Appl. Phys., 59 (1986) 1341), we predict, without any phenomenological assumption, that the volume distribution behaves as v(2−D)/D (where D is the dimension of space) in the limit of small volumes. This is in agreement with recent experimental results. In the self-similar growth regime, we validate experimentally a relation between the bubbles' growth rates and their size distribution. In 2D, we discuss the relation between the areas distribution and the correlation between edge numbers and bubble area
