Optimal cement paste yield stress for the production of stable cement foams
Blandine Feneuil, Nicolas Roussel, Olivier Pitois
Production of morphology-controlled cement foams remains challenging, mainly due to bubble stability issues during cement setting. The use of cement paste with high yield stress is…
Stability of Big Surface Bubbles: Impact of Evaporation and Bubbles Size
Jonas Miguet, Marina Pasquet, Florence Rouyer +2
Surface bubbles have attracted much interest in the past decades. In this article, we propose to explore the lifetime and thinning dynamics of centimetric surface bubbles. We study…
Rheology and microstructure of unsaturated granular materials: Experiments and simulations
M. Badetti, A. Fall, F. Chevoir +3
When dealing with unsaturated wet granular materials, a fundamental question is: what is the effect of capillary cohesion on the bulk flow and yield behavior? We inwestigate the de…
Permeability of porous foamy materials
V. Langlois, V. H. Trinh, C. Lusso +4
In this paper, we study the effects of both the amount of open cell walls and their aperture sizes on solid foams permeability. FEM flow simulations are performed at both pore and…
Coupled elasticity in soft solid foams
François Gorlier, Yacine Khidas, Olivier Pitois
Elasticity of soft materials can be greatly influenced by the presence of air bubbles. Such a capillary effect is expected for a wide range of materials, from polymer gels to conce…
Optimal strengthening of particle-loaded liquid foams
François Gorlier, Yacine Khidas, Abdoulaye Fall +1
Foams made of complex fluids such as particle suspensions have a great potential for the development of advanced aerated materials. In this paper we study the rheological behavior…
Flow of wet granular materials: a numerical study
Saeed Khamseh, Jean-Noël Roux, François Chevoir
We simulate dense assemblies of frictional spherical grains in steady shear flow under controlled normal stress in the presence of a small amount of an interstitial liquid, whi…
Flow and Jamming of Granular Suspensions in Foams
B. Haffner, Y. Khidas, O. Pitois
The drainage of particulate foams is studied under conditions where the particles are not trapped individually by constrictions of the interstitial pore space. The drainage velocit…
Rheology of sedimenting particle pastes
Abdoulaye Fall, Henri de Cagny, Daniel Bonn +4
We study the local and global rheology of non-Brownian suspensions in a solvent that is not density-matched, leading to either creaming or sedimentation of the particles. Both loca…
A comparative study of crumpling and folding of thin sheets
Stephanie Deboeuf, Eytan Katzav, Arezki Boudaoud +2
Crumpling and folding of paper are at rst sight very di erent ways of con ning thin sheets in a small volume: the former one is random and stochastic whereas the latest one is regu…
Anisotropic nonlinear elasticity in a spherical bead pack: influence of the fabric anisotropy
Yacine Khidas, Xiaoping Jia
Stress-strain measurements and ultrasound propagation experiments in glass bead packs have been simultaneously conducted to characterize the stress-induced anisotropy under uniaxia…
Permeability of a bubble assembly: From the very dry to the wet limit
Florence Rouyer, Olivier Pitois, Elise Lorenceau +1
We measure the permeability of a fluidized bed of monodispersed bubbles with soap solution characteristic of mobile and non-mobile interfaces. These experimental data extend the pe…
Three-dimensional jamming and flows of soft glassy materials
Guillaume Ovarlez, Quentin Barral, Philippe Coussot
Various disordered dense systems such as foams, gels, emulsions and colloidal suspensions, exhibit a jamming transition from a liquid state (they flow) to a solid state below a yie…
Yield stress and shear-banding in granular suspensions
Abdoulaye Fall, Francois Bertrand, Guillaume Ovarlez +1
We study the emergence of a yield stress in dense suspensions of non-Brownian particles, by combining local velocity and concentration measurements using Magnetic Resonance Imaging…
Probing viscoelastic properties of a thin polymer film sheared between a beads layer and quartz crystal resonator
Julien Leopoldes, Xiaoping Jia
We report measurements of viscoelastic properties of thin polymer films of 10-100 nm at the MHz range. These thin films are confined between a quartz crystal resonator and a millim…
Curvature in conformal mappings of 2D lattices and foam structure
A. Mughal, D. Weaire
The elegant properties of conformal mappings, when applied to two dimensional (2D) lattices, find interesting applications in 2D foams and other cellular or close packed structures…
