Yielding dynamics of a Herschel–Bulkley fluid: a critical-like fluidization behaviour
Yielding dynamics of a Herschel–Bulkley fluid: a critical-like fluidization behaviour
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 widths and boundary conditions. As already described in [Divoux et al., {\it Phys. Rev. Lett.}, 2010, {\bf 104}, 208301], we show that the fluidization process of …
