Abstract.We study the two-dimensional flow of foams around a
circular obstacle within a long channel. In experiments, we
confine the foam between liquid and glass surfaces. In
simulations, we use a deterministic software, the Surface
Evolver, for bubble details and a stochastic one, the extended
Potts model, for statistics. We adopt a coherent definition of
liquid fraction for all studied systems. We vary it in both
experiments and simulations, and determine the yield drag of the
foam, that is…

The results exhibit a power-law dependence of the drag as a function of the bulk viscosity and the flow rate with two different exponents, and it is shown that the drag decreases with bubble size and increases proportionally to the obstacle size.

Under conditions of sufficiently slow flow, foams, colloids, granular matter, and various pastes have been observed to exhibit shear localization, i.e., regions of flow coexisting with regions of solidlike behavior; it is found that the top plate dramatically alters both the velocity profile and the distribution of nonlinear rearrangements, even at these slow rates of strain.
