HiFi-MuTaNTS

High Fidelity Multiscale solute Transport modeling in Nanoporous media under fluctuating Thermodynamic and Saturation conditions

Quantification and prediction of solute movement within nanoporous materials like clays and cements are crucial in many applications, including long-term safety and storage of nuclear waste, waste management, mining, energy systems, and environmental protection. Despite extensive studies in the last decades, research gaps remain, especially in understanding how temperature and water saturation affect solute/pollutant transport behavior through these materials.

HiFi-MuTaNTS project proposes a model-based scientific investigation and develops an advanced computer modeling framework. By simulating processes at various scales, from the atomistic to continuum, the project aims to reveal how temperature and saturation fluctuations influence solute transport and chemical reactions in these materials. Results will provide new scientific understanding and quantitative tool that will significantly improve waste disposal strategies and sustainable resource management practices. The developed modeling tools and parameter databases will also benefit the research community and practitioners globally, enabling accurate assessment and prediction in waste and water management applications.

CSC’s role is to support the project group in porting codes to LUMI and GPUs in general and developing ground water flow capabilities of the Elmer FEM multi-physics modeling software.
