Generalized Hydrodynamics with Viscoplasticity for Channeling in Saturated Sand
Abstract
In this report we review the "Generalized Formulation of Hydrodynamics" for a single incompressible species with free surfaces and consider methods to extend this formulation to the multiple species case. Constraints on the species volume fractions are imposed using successive redistribution. Formulations that include material strength and viscosity are described. A non-Newtonian viscous model, which approximates a Bingham plastic model, is described and implemented. Benchmark computations are performed to assess the accuracy of the computational model. Numerical simulations of explosive channeling in sand under a layer of water arc presented with some comparisons to experimental data.
