Abstract

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.
