ABSTRACT

Validation of a 3-D, finite clement, multi-phase code, FEHMN (Finite Element Heat and Mass Nuclear) developed at Los Alamos National Laboratory was performed. Results from an isothermal 2-D tank experiment involving the injection of a dense NAPL into an initially water-saturated, 3-layered heterogeneous porous medium were used for validation of the code. Quantitative data obtained during the experiment include saturation distributions within the 2-D tank at various times using a dual gamma system, injected mass of NAPL over time, and visual propagation of the NAPL front dyed red. Based on the results of the numerical simulations, additional, more focused 2-D tank experiments were proposed for further model validation. This validated model will be used in our future research efforts on up-scaling of multi-phase flow parameters to field problems.
