Fluid-rock interaction experiments with andesite at 100°C for potential carbon storage in geothermal reservoirs (2024)
Journal Article

Geothermal energy extraction often results in the release of naturally occurring carbon dioxide (CO2) as a byproduct. Research on carbon storage using volcanic rock types other than basalt under both acidic and elevated temperature conditions has bee...

Modelling the influence of mechanical-ecohydrological feedback on the nonlinear dynamics of peatlands (2023)
Journal Article

Peatlands are complex systems that exhibit nonlinear dynamics due to internal and external feedback mechanisms. However, the feedback of vegetation on peat volume changes that potentially affect peatland dynamics is not well understood. Here, we anal...

MPeat—A fully coupled mechanical-ecohydrological model of peatland development (2021)
Journal Article

Mathematical models of long-term peatland development have been produced to analyse peatland behaviour. However, existing models ignore the mechanical processes that have the potential to provide important feedback. Here, we propose a one-dimensional...

Pore-Scale Modeling of Fluid–Rock Chemical Interactions in Shale during Hydraulic Fracturing (2021)
Journal Article

During the hydraulic fracturing process in unconventional shale gas reservoirs, chemical interactions between the hydraulic fracturing fluid (HFF) and the shale rock could result in mineral precipitation and dissolution reactions, potentially influen...

The architectural design of smart ventilation and drainage systems in termite nests (2019)
Journal Article

Termite nests have been widely studied as effective examples for ventilation and thermoregulation; however, the mechanisms by which the nest properties are controlled by the micro-structure of the outer walls remain unclear. Here, we combine multi-sc... Read More about The architectural design of smart ventilation and drainage systems in termite nests.

Modelling and upscaling of transport in carbonates during dissolution: validation and calibration with NMR experiments (2017)
Journal Article

We present an experimental and numerical study of transport in carbonates during dissolution and its upscaling from the pore (∼ μm) to core (∼ cm) scale. For the experimental part, we use nuclear magnetic resonance (NMR) to probe molecular displaceme...

Multiscale method for Oseen problem in porous media with non-periodic grain patterns (2016)
Journal Article

Accurate prediction of the macroscopic flow parameters needed to describe flow in porous media relies on a good knowledge of flow field distribution at a much smaller scale---in the pore spaces. The extent of the inertial effect in the pore spaces ca... Read More about Multiscale method for Oseen problem in porous media with non-periodic grain patterns.

Nonconforming multiscale finite element method for Stokes flows in heterogeneous media. Part I: Methodologies and numerical experiments (2015)
Journal Article

The multiscale finite element method (MsFEM) is developed in the vein of the Crouzeix--Raviart element for solving viscous incompressible flows in genuine heterogeneous media. Such flows are relevant in many branches of engineering, often at multiple... Read More about Nonconforming multiscale finite element method for Stokes flows in heterogeneous media. Part I: Methodologies and numerical experiments.

The impact of porous media heterogeneity on non-Darcy flow behaviour from pore-scale simulation (2015)
Journal Article

The effect of pore-scale heterogeneity on non-Darcy flow behaviour is investigated by means of direct flow simulations on 3-D images of a beadpack, Bentheimer sandstone and Estaillades carbonate. The critical Reynolds number indicating the cessation... Read More about The impact of porous media heterogeneity on non-Darcy flow behaviour from pore-scale simulation.

Crouzeix-Raviart MsFEM with bubble functions for diffusion and advection-diffusion in perforated media (2015)
Journal Article

The adaptation of Crouzeix-Raviart finite element in the context of multi-scale finite element method (MsFEM) is studied and implemented on diffusion and advection-diffusion problems in perforated media. It is known that the approximation of boundary... Read More about Crouzeix-Raviart MsFEM with bubble functions for diffusion and advection-diffusion in perforated media.
