2D granular flows with the $\mu (I)$ rheology and side walls friction: a well balanced multilayer discretization

E. D. Fernández-Nieto, J. Garres-Díaz, A. Mangeney +1

We present here numerical modelling of granular flows with the $\mu (I)$ rheology in confined channels. The contribution is twofold: (i) a model to approximate the Navier-Stokes equat…
