[AHW28-P13] Applying THMC Model with User-Friendly Interface to Reactive Advection-Dispersion Transport Problem
Keywords:THMC model , reactive transport simulation , groundwater remediation , advection-dispersion process
THMC (Thermal-Hydrological-Mechanical-Chemical) model, developed by the prestigious hydrologist Prof. Gour-Tsyh Yeh, is an advanced physics-based FEM model designed to simulate fully coupled processes in both saturated and unsaturated subsurface environments. Designed to tackle a wide range of water-related challenges, THMC excels in areas such as carbon sequestration, geothermal energy, nuclear waste disposal, groundwater resource management and groundwater remediation.
Recent improvements in THMC model emphasize enhanced simulation accuracy and computational stability, solidifying its reputation as a leading solution in the global subsurface software market. Additionally, CAMRDA at National Central University, Taiwan, has greatly enhanced the model's usability by creating a Windows-based, user-friendly interface. This platform supports full 3D operations, ensuring seamless simulation workflows, interactive visualization, and intuitive model-building capabilities. Its proprietary 2D/3D mesh generation engine enables efficient creation of detailed conceptual models and simulation-ready meshes.
To make the software more feasible, it integrates a comprehensive database of commonly used parameters, including material coefficients and chemical equations. This simplifies the setup process and reduces the learning curve for new users. With these upgrades, THMC has become a competitive and versatile tool for researchers and practitioners addressing complex environmental and engineering challenges.
This study demonstrates the application of THMC model in simulating the reactive advection-dispersion transport of contaminant in a subsurface environment. The example models a hypothetical clean-up process by continuously recharging clean water into a contaminated domain, considering complex interactions including adsorption and desorption. Results show that, as clean water is injected, dissolved concentrations of contaminant decrease over time, particularly in regions with higher adsorption-site concentrations. Additionally, pH values decrease as the clean water is recharged, highlighting the model’s capability to simulate complex transport and remediation processes effectively.
