Mixtures of foam and paste: suspensions of bubbles in yield stress fluids
Michael Kogan, Lucie Ducloué, Julie Goyon +3
We study the rheological behavior of mixtures of foams and pastes, which can be described as suspensions of bubbles in yield stress fluids. Model systems are designed by mixing mon…
Damage in porous media due to salt crystallization
Noushine Shahidzadeh-Bonn, Julie Desarnaud, François Bertrand +2
We investigate the origins of salt damage in sandstones for the two most common salts: sodium chloride and sulfate. The results show that the observed difference in damage between…
Flows and heterogeneities with a vane tool: Magnetic resonance imaging measurements
Guillaume Ovarlez, Fabien Mahaut, François Bertrand +1
We study the local flow properties of various materials in a vane-in-cup geometry. We use magnetic resonance imaging techniques to measure velocities and particle concentrations in…
Homogenization approach to the behavior of suspensions of noncolloidal particles in yield stress fluids
Xavier Chateau, Guillaume Ovarlez, Kien Luu Trung
The behavior of suspensions of rigid particles in a non-Newtonian fluid is studied in the framework of a nonlinear homogenization method. Estimates for the overall properties of th…
