Verficication of numerical tools through thermo-hydro-gas (THG) modeling for a geological repository in boom clay

Research output › peer-review

Abstract

Verification of two numerical tools, TOUGH2-EOS5 module and CODE_BRIGHT, is carried out through three benchmark cases, including a 1D hydro-gas (HG) case, a 2D axi-symmetrical HG case with a constant hydrogen production rate, and a 2D axisymmetrical thermo-hydro-gas (THG) case with time-varying heat and gas production rate. These benchmark cases for modeling the gas-driven migration of pore water under the combined effects of high gas pressure and high temperature are based on the Belgian multibarrier repository design for disposal of high-level waste (HLW). Comparisons between numerical results demonstrate that these two numerical tools give quite similar results in all three benchmark cases, thus providing evidence for the validity of these tools in solving HG and THG problems. The differences in the results obtained by two modeling tools are also analyzed.
