The compressible granular collapse in a fluid as a continuum: validity of a Navier-Stokes model with $\mu (J)$-$\varphi (J)$-rheology

Matthias Rauter

The incompressible $\mu (I)$-rheology has been used to study subaerial granular flows with remarkable success. For subaquatic granular flows, drag between grains and the pore fluid is…
