Abstract

In this project, my group will conduct multiphysics simulations of fully-coupled thermo-hydro-mechanical-chemical processes in fractured porous media. We adopt the discrete fracture network approach which will explicitly capture the distribution and behaviour of multiscale fracture networks in geological media. We will computationally solve the couplings among various physical processes such as heat transfer, fluid flow, mechanical deformation, and chemical reaction based on the finite element method. We will apply this multiscale, multiphysics computational framework to study a wide range of geoscience and geoengineering problems such as fluid injection, heat production, induced seismicity, tunnel excavation, seismic attenuation, carbon sequestration, and karst evolution.
