Discontinuous Shear Thickening (DST) transition with spherical iron particles coated by adsorbed brush polymer
Georges Bossis, Yan Grasselli, Olga Volkova
In this work we explore the rheology of very concentrated (0.55<<0.67) suspensions of carbonyl iron (CI) particles coated by a small polymer. A strong DST is observed in a large…
Capillary flow of a suspension in the presence of discontinuous shear thickening
Georges Bossis, Yan Grasselli, Olga Volkova
The rheology of suspensions showing discontinuous shear thickening (DST) is well documented in conventional rheometer with rotating tools, but their study in capillary flow is stil…
Tunable discontinuous shear thickening in capillary flow of MR suspensions
Georges Bossis, Yan Grasselli, Alain Ciffreo +1
Very concentrated suspensions of iron particles in water or ethylene glycol can be obtained thanks to the use of superplasticizer molecules used in cement industry. At high volume…
Translational and rotational temperatures of a 2D vibrated granular gas in microgravity
Yan Grasselli, Georges Bossis, Romain Morini
We present an experimental study performed on a vibrated granular gas enclosed into a 2D rectangular cell. Experiments are realized in microgravity. High speed video recording and…
Granular Rheology in Zero Gravity
G. Bossis, Y. Grasselli, O. Volkova
We present an experimental investigation on the rheological behavior of model granular media made of nearly elastic spherical particles. The experiments are performed in a cylindri…
Effect of impact energy on the shape of granular heaps
Yan Grasselli, Hans J. Herrmann, Gadi Oron +1
We study experimentally the shape of a granular heap formed pouring a granular material into a vertical Hele-Shaw cell and analyze the effect of the grain impact energy. We propose…
