Quantitative predictions of the μ(I) rheology in 2D and 3D granular column collapse: scaling laws and quasi-static vs. inertial regimes
Abstract : We introduce an accurate numerical method for the computation of 2D and 3D granular collapse under gravity flows using the μ(I) rheology. We show that this rheology can capture the two experimentally observed types of spreading and the corresponding scaling laws, and we provide an accurate sensitivity analysis to rheological constants. Finally, we underline the role of time-dependency on the spreading dynamics.
