Avalanches of popping bubbles in collapsing foams.
نویسندگان
چکیده
We report acoustic measurements of popping bubbles during the collapsing of aqueous foams. The sound pattern is analyzed using classical methods of statistical physics. It is found that membrane rupture concerns a wide variety of situations: small and large membranes at the air/foam interface. Avalanches of popping bubbles are put into evidence. Time durations in between successive pops seem to be distributed on a universal power law.

Simulation of Foaming and Deformation for Composite Aluminum Foams
In this study, at the first stage, the rupture criterion of bubbles wall in Aluminum metal foam liquid was investigated by using Lattice Boltzmann. The two phases modeling were accomplished by using a modified Shan-Chen model. This model was run for several bubbles in A356+3wt.%SiC melt system. Then, bubbles morphologies (virtual metallographic) for A356+3wt.%SiC foams were simulated. Results s...
متن کاملHysteresis and avalanches in two-dimensional foam rheology simulations.
Foams have unique rheological properties that range from solidlike to fluidlike. We study two-dimensional noncoarsening foams of different disorder under shear in a Monte Carlo simulation, using a driven large-Q Potts model. Simulations of periodic shear on an ordered foam show several different response regimes. At small strain amplitudes, bubbles deform and recover their shapes elastically, a...
متن کاملEffect of Fe additive on plastic deformation for crush-boxes with closed-cell metal foams, Part I: Al-composite foam compression response
AbstractIn this paper, we investigate effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as filler of thin-walled tubes. However, deformation of the Aluminum foam-filled thin-walled tubes as crushed-box will be presented in Part (II). Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as closed cell were synthesized by powder metallurgy foaming metho...
متن کاملCyclic deformation of bidisperse two-dimensional foams
In-plane deformation of foams was studied experimentally by subjecting bidisperse foams to cycles of traction and compression at a prescribed rate. Each foam contained bubbles of two sizes with given area ratio and one of three initial arrangements: sorted perpendicular to the axis of deformation (iso-strain), sorted parallel to the axis of deformation (iso-stress), or randomly mixed. Image ana...
متن کاملThe mixing of bubbles in two-dimensional bidisperse foams under extensional shear
Two-dimensional bidisperse foams were simulated in cyclic, uniaxial, extensional shear. Mixing of bubbles of different sizes only occurs at high strains, and once mixed, the bubbles do not segregate. For liquid fractions up to 1%, the rate of mixing is shown to be slightly enhanced by increased liquid fraction.
