Emergence of non-Fickian transport in truncated pluri-Gaussian permeability fields (2022)
Journal Article

We present a numerical simulation study of advective–diffusive scalar transport in three-dimensional high-contrast discontinuous permeability fields, generated with a truncated pluri-Gaussian geostatistical approach. The numerical experiments are run... Read More about Emergence of non-Fickian transport in truncated pluri-Gaussian permeability fields.

A systematic analysis of the memory term in coarse-grained models: The case of the Markovian approximation (2022)
Journal Article

The systematic development of coarse-grained (CG) models via the Mori–Zwanzig projector operator formalism requires the explicit description of a deterministic drift term, a dissipative memory term and a random fluctuation term. The memory and fluctu... Read More about A systematic analysis of the memory term in coarse-grained models: The case of the Markovian approximation.

Population Balance Models for Particulate Flows in Porous Media: Breakage and Shear-Induced Events (2022)
Journal Article

Transport and particulate processes are ubiquitous in environmental, industrial and biological applications, often involving complex geometries and porous media. In this work we present a general population balance model for particle transport at the...

Mathematical Modeling and Pilot Test Validation of Nanoparticles Injection in Heavy Hydrocarbon Reservoirs (2022)
Journal Article

Heavy-oil mobility in reservoir rocks can be improved, using nanotechnology, by reducing the viscosity of the oil and improving the rock wettability to a water-wet condition. Previous pilot studies in Colombian heavy oil fields reported that nanopart...

Liquid film distribution around long gas bubbles propagating in rectangular capillaries (2022)
Journal Article

We present a systematic analysis of the bubble and liquid film dynamics corresponding to the propagation of long, isolated gas bubbles, within rectangular capillary channels of cross-sectional aspect-ratio ranging from 1 to 8. Direct numerical simula... Read More about Liquid film distribution around long gas bubbles propagating in rectangular capillaries.
