Bottom: Differences in compaction schemes for two reactive transport models ToughReact and CrunchFlow.
Scientific Achievement
We present a comprehensive mathematical description of multi-component, multi-phase, flow and reactive transport processes at the continuum-scale as well as various constitutive relationships to parameterize the heterogeneous subsurface system under variably saturated conditions.
Significance and Impact
There is a growing need to benchmark reactive transport codes. The geosciences community has made significant efforts to benchmark reactive transport codes. A summary of such efforts is presented here.
Research Details
- Provided a description of governing equations, numerical schemes including coupling and solution approaches
- Included a thorough literature review on the benchmarking needs for developing standardized references, codes, models, conceptual model comparisons, performance and reliability
- Described benchmarking activities initiated within the last several years by the geosciences community, including the SSBench initiative
