Journal Article
Muljadi, B. P., Bijeljic, B., Blunt, M. J., Colbourne, A., Sederman, A. J., Mantle, M. D., & Gladden, L. F. (in press). Modelling and upscaling of transport in carbonates during dissolution: validation and calibration with NMR experiments. Journal of Contaminant Hydrology, https://doi.org/10.1016/j.jconhyd.2017.08.008

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...

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.

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.

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.
