Journal Article
Pescimoro, E., Icardi, M., Porta, G., & Bianchi, M. (2022). Emergence of non-Fickian transport in truncated pluri-Gaussian permeability fields. GEM - International Journal on Geomathematics, 13, Article 17. https://doi.org/10.1007/s13137-022-00207-4

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
Di Pasquale, N., Hudson, T., Icardi, M., Rovigatti, L., & Spinaci, M. (2023). A systematic analysis of the memory term in coarse-grained models: The case of the Markovian approximation. European Journal of Applied Mathematics, 34(2), 326-345. https://doi.org/10.1017/s0956792522000158

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
Valencia, J. D., Mejía, J. M., Icardi, M., & Zabala, R. (2022). Mathematical Modeling and Pilot Test Validation of Nanoparticles Injection in Heavy Hydrocarbon Reservoirs. Fluids, 7(4), Article 135. https://doi.org/10.3390/fluids7040135

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.
