The purpose of this internship is to start investigating the pressure-imposed rheology (PIR) of suspensions [3,4], a state-of-the-art method to characterize quantitatively suspensions up to the critical volume friction at which the viscosity diverges. Part of the internship will be dedicated to the finalization of the PIR tool currently developed at MSC. Then, work will revolve around the characterization of the mechanical response of model suspensions developed between MSC and SIMM under imposed pressure. In particular we will focus on frictionless suspensions, as their response to flow is still essentially unknown. Theoretical propositions exist in the literature to which the data will be compared. This work may lead to a PhD, subject to the smooth progress of the internship. Th eproject is supported by an ANR grant.
