Rheology of dense granular suspensions across flow regimes

The objective of this work is to establish a unified theoretical framework for the rheology of dense granular suspensions across different flow regimes. By conducting rheological measurements at imposed volume fractions or at imposed values of particle normal stress, a unified granular rheology can be proposed across the viscous to inertial flow regime. This granular rheology, identified for suspensions of hard spheres, can be extended to a soft granular rheology for soft particles.
