摘要

We provide a suite of verification examples for coupled thermo-hydro-mechanical (THM) processes in subsurface flow. The considered scenarios are subsets of THM problems with and without fractures. The examples include classical problems presented by Terzaghi, Schiffman, Mandel, Wijesinghe, McNamee and Gibson, Noda and Lauwerier. For each example, we provide a description of the physical problem setup, the governing equations, the solution to the equation, and comparison of that solution with a new THM simulator. Python scripts for the solutions are available in a Git repository for other modeling groups to verify their own THM simulators. We demonstrate this new verified simulator’s full THM capabilities by modeling a hypothetical enhanced geothermal system to show how dynamically modifying fracture aperture impacts energy production over a period of ten years.
