Yielding dynamics of a Herschel-Bulkley fluid: a critical-like fluidization behaviour
Thibaut Divoux, David Tamarii, Catherine Barentin +2
The shear-induced fluidization of a carbopol microgel is investigated during long start-up experiments using combined rheology and velocimetry in Couette cells of varying gap width…
Degassing cascades in a shear-thinning viscoelastic fluid
Valérie Vidal, François Soubiran, Thibaut Divoux +1
We report the experimental study of the degassing dynamics through a thin layer of shear-thinning viscoelastic fluid (CTAB/NaSal solution), when a constant air flow is imposed at i…
Influence of Non-Newtonian rheology on magma degassing
Thibaut Divoux, Valérie Vidal, Maurizio Ripepe +1
Many volcanoes exhibit temporal changes in their degassing process, from rapid gas puffing to lava fountaining and long-lasting quiescent passive degassing periods. This range of b…
Stress overshoot in a simple yield stress fluid: an extensive study combining rheology and velocimetry
Thibaut Divoux, Catherine Barentin, Sebastien Manneville
We report a large amount of experimental data on the stress overshoot phenomenon which takes place during start-up shear flows in a simple yield stress fluid, namely a carbopol mic…
