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… 
Two-dimensional flow of foam around a circular obstacle: local measurements of elasticity, plasticity and flow
We investigate the two-dimensional flow of a liquid foam around a circular obstacle by measuring all the local fields necessary to describe this flow: velocity, pressure, and bubble deformations and
Flow of foam through a convergent channel
Abstract.We study experimentally the flow of a foam confined as a bubble monolayer between two plates through a convergent channel. We quantify the velocity, the distribution and orientation of
Probing the local response of a two-dimensional liquid foam
Aqueous foams are viscoelastic yield stress fluids. Due to their complex rheology, foam flow around an obstacle embedded in a 2D Hele-Shaw cell has been widely studied. Typically, in such geometry in
Simulations of bubble division in the flow of a foam past an obstacle in a narrow channel
When foams flow through porous media, the interaction of the lamellae with the walls of the channels leads to changes in the bubble size distribution. We predict these changes using Surface Evolver

Foam flows through a local constriction
We present an experimental study of the flow of a liquid foam, composed of a monolayer of millimetric bubbles, forced to invade an inhomogeneous medium at a constant flow rate. To model the simplest
A computational method to simulate mono- and poly-disperse two-dimensional foams flowing in obstructed channel
A modified phase-field model is presented to numerically study the dynamics of flowing foam in an obstructed channel. The bubbles are described as smooth deformable fields interacting with one
Foam flow around an obstacle: simulations of obstacle–wall interaction
The flow of a two-dimensional foam around an obstacle provides a benchmark experiment in which to study the transition from discrete to continuous properties of this complex fluid. The interaction
Dissipation in quasi-two-dimensional flowing foams
The dissipation between two-dimensional (2D) monolayers of bubbles, the so-called quasi-2D foams, and a wall is investigated in two setups: a ''liquid pool'' system, where the foam is confined

Two-dimensional flow of foam around an obstacle: force measurements.
TLDR
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.
Two-dimensional flows of foam: drag exerted on circular obstacles and dissipation
A Stokes experiment for foams is proposed. It consists in a two-dimensional flow of a foam, confined between a water subphase and a top plate, around a fixed circular obstacle. We present systematic
Flow of foam past an elliptical obstacle.
TLDR
A microscopic visco-elasto-plastic model is proposed which agrees qualitatively with the data on the link between discrete small-scale and continuous large scale mechanical properties of a foam.

Stokes experiment in a liquid foam
The paper reports on the quasistatic steady flow of a dry liquid foam around a fixed spherical bead, a few times larger than the typical bubble size. The force exerted on the bead is recorded with a
Two-bubble instabilities in quasi-two-dimensional foams
We study the effect of the experimental set-up on the structure and rheology of two-dimensional foams. We perform the same experiment, in which a sequence of topological instabilities is realized, in
Dissipation in foam flowing through narrow channels
We present measurements on simple foam structures flowing through a narrow channel. Driving pressure and bubble velocity are found to be related by a power law with exponent 2/3, thus extending this
Transient and steady-state drag in foam
The steady-state force exerted on a sphere moving at constant speed through an aqueous foam is studied experimentally. The dependence of the force on container size indicates that the moving sphere
Impact of boundaries on velocity profiles in bubble rafts.
TLDR
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.

Wall-slip is an important phenomenon for the rheological behavior of various dispersions, including foams. In a previous study [N.D. Denkov et al., Coll. Surf. A 263 (2005) 129] we showed
