| In this presentation, we describe our micro-macro, multi-scale approach to non-Newtonian free-surface flows. The method uses, at the macroscopic scale, a particle level-set technique along with a semi-Lagrangian, finite element discretization; the microscopic scale is described via variance-reduced, Brownian Dynamics simulations of Hook (Oldroyd-B) and FENE dumbbells. The resulting Stokes problems including the (polymer) extra-stress tensor are efficiently solved using PETSc. We show numerical tests in the rising bubble configuration, for Newtonian and non-Newtonian (Hooke, FENE) fluids, which run in a commodity, multi-core PC. | |
