Numerical simulation of the miscible displacement of radionuclides in a heterogeneous porous medium
The aim of this paper is to model and simulate the displacement of radioactive elements in a saturated heterogeneous porous medium. New schemes are proposed to solve accurately the convection-diffusion-reaction equations including nonlinear terms in the time derivative. Numerical tests show the stability and robustness of these schemes through strong heterogeneities of the medium. Finally the COUPLEX I benchmark concerning the far field Simulation Of a Polluted flow by a leak of a nuclear waste disposal is performed and compared with the results available in the literature.
