Experimental Growth Law for Bubbles in a Moderately ''Wet'' 3D Liquid Foam

Résumé

We used x-ray tomography to characterize the geometry of all bubbles in a liquid foam of average liquid fraction ϕl≈17% and to follow their evolution, measuring the normalized growth rate G=V-1/3(dV)/(dt) for 7000 bubbles. While G does not depend only on the number of faces of a bubble, its average over f-faced bubbles scales as Gf˜f-f0 for large f's at all times. We discuss the dispersion of G and the influence of V and ϕl on G.
