Abstract

A numerical model, called CSTCRS1, is presented for coupled one-dimensional large-strain consolidation and solute transport under constant rate of strain (CRS) loading conditions. The model is based on a dual-Lagrangian framework that tracks separately the motions of fluid and solid phases. A series of numerical simulations indicates that transport boundary conditions can have an important effect on the solute transport during CRS consolidation. The zero concentration boundary condition yielded the largest solute mass outflows, the reservoir boundary condition yielded intermediate values, and the zero concentration gradient boundary condition yielded the smallest outflows. Additional simulations indicate that, for conditions considered, increasing the applied strain rate will generally decrease solute mass outflow.
