Methodology
  • The finite volume method (FVM) of the multi-phase flow is applied. The spatial discretization is of the second order. The first-order simple implicit scheme is applied for time discretization. The PISO algorithm is applied to iteratively solve the momentum and pressure equations. The advection equation for the phase fraction is solved using the explicit Euler time discretization and the spatial discretization by the MULES scheme based on the upwind interpolation outside the interface areas and a delimiter-based combination of the linear and upwind interpolations inside it. The use of the compressive fluxes allows the solver to restrict the numerically diffused interface thickness to a few (typically two or three in our simulations) cell widths.
Description
  • The Liquid Metal Battery (LMB), a promising energy-storage device that contains liquid-metal interior, is studied numerically in the paper. The metal pad roll instability was modeled based on the open-source CFD software, OpenFOAM. It's based on the solver for simulations of incompressible multiphase flows multiphaseInterFoam modified to include the electromagnetic fields and account for the sharp variations of the electrical conductivity.
