Physical modeling and particle-scale simulations of adhesive colloidal suspensions
The project aims at studying how the rheology of concentrated adhesive suspensions emerges from their microstructure and physico-chemistry. Such systems often present nonspherical particles, that engage in complex interactions combining colloidal, hydrodynamic, and contact forces. The project targets suspensions of direct relevance to construction and environmental materials such as fresh cement and clays: it will simulate realistic models of these systems and use them to identify the physical mechanisms responsible for their macroscopic rheological properties (thixotropy, non-associated flow rules,…).
