Dear InterPore colleagues,
Happy New Year! Certainly to those living with the Gregorian Calendar, but also the
best wishes to all those living with other calendars,
still awaiting their New Years Eve, as best wishes never hurt!
Today’s Newsletter looks backwards (two nice publications came online at the end of
2021) and looks ahead (InterPore2022, job opportunities) and we can at the very
start of this new year already announce a new InterPore Award winner.
How is that for a great start to 2022!

Special notice
While the uncertainties around the pandemic remain, there is no doubt that we will
meet in 2022! We are very optimistic about gathering in Abu Dhabi, and are planning
a dynamic and educational hybrid conference which will be accessible from anywhere
in the world.
Abstract submission is open!
Abstract submission deadline is only just over 2 weeks away! Abstracts can be
submitted for oral and poster presentations as in-person or online in 24
minisymposia. The submission deadline is Monday, 17 January 2022.

Minisymposium in honor of Prof. Sjoerd van der Zee
InterPore is recognizing the scientific achievements of Prof.
Sjoerd
van der Zee (WUR, The Netherlands), by dedicating a minisymposium to his
works during its upcoming annual
meeting, 30 May – 02 June 2022, Abu Dhabi, United Arab Emirates, as well as online.
The minisymposium is entitled (MS02) Porous
Media for a Green World: Water & Agriculture. We invite all
collaborators of Sjoerd to submit abstracts to this minisymposium. Sjoerd will be
joining online.
Invited Speaker
Dr. Ruina
Xu from Tsinghua University will present a talk entitled Supercritical
CO2 flow and heat/mass transfer in micro/nano-porous structures in CO2
geological utilization and storage.
Ruina Xu is an Associate Professor (tenured) of the Department of Energy and Power
Engineering at Tsinghua University and Deputy Director of the Key Laboratory for CO2
Utilization and Reduction Technology of Beijing. Her research aims at providing
answers to fundamental questions on the dynamics of multiphase flow, heat and mass
transfer in micro-/nano-scale and complex porous networks.
CO2 geological storage and its use to enhance geothermal systems and shale oil/gas
recovery are critical technologies for addressing climate change. CO2 is in a
supercritical condition among the above methods. One of the most important
challenges in improving recovery efficiency and long-term storage safety is the
migration and heat/mass transfer of supercritical fluids in reservoir porous
structures. Under the …read

Minisymposia Spotlight
In the interdisciplinary spirit from which the InterPore society was born, the
minisymposia provide a forum where investigators and technicians from
disparate fields can come together and display their commonality of problems,
investigatory techniques and solution strategies.
(MS12) Advances in
modeling and simulation of poromechanics

- Joshua White
In the past decade, the numerical simulation of coupled mechanical deformation and
fluid flow in porous media, shortly poromechanics, has become of increasing
importance in several branches of technology and natural sciences. Among typical
societal relevant applications of poromechanics we mention geothermal energy
extraction, CO2 storage, hydraulic fracturing or cancer research. In this
mini-symposium we will address recent developments in numerical solvers for
poromechanics, e.g. iterative and monolithic schemes, multigrid, efficient
preconditioners and (stable / multiscale / mass conservative) discretization
methods. In the same time new trends …read

In most natural or technological processes the pores contain fluids: water in clays
and concrete, hydrocarbons in coal and shale, etc. In nanopore-confined fluid, tight
spatial confinement and solid-fluid interactions may significantly alter the fluid’s
physical properties, causing, for example, the molecular structuring of the fluid,
shifts of the freezing or evaporation points and the appearance of the disjoining
pressure. The objective of this minisymposium is to provide a forum for the
discussion of all possible aspects of fluid phases confined in nanoporous materials:
fundamental and applied, theoretical and experimental. read

The goal of this minisymposium is to provide a forum for discussion of common themes
that arise in the application of stochastic (e.g., Markov chain Monte Carlo (McMC))
and deterministic (e.g. adjoint formulation) uncertainty quantification (UQ) methods
for porous media. We welcome UQ methods for all porous media applications, including
flow in porous media and geophysics. We aim for a multi-disciplinary minisymposium
that forms a basis for cross-discipline discussions of new findings, challenges, and
methods forward. We welcome contributions on HPC, machine learning, and multiscale
methods that aim at speeding up computations related to UQ. read

The InterPore Time Capsule Award goes to Professor Emeritus Gedeon
Dagan of Tel Aviv University, Israel. Dagan is interviewed by Professor
Vladimir Cvetkovic of KTH Royal Institute of Technology (Stockholm, Sweden). Dagan
is a pioneer in developing stochastic subsurface hydrology with particular emphasis
on groundwater flow and contaminant transport in heterogeneous aquifers. He talks
about his early interest in mathematics and engineering, what shaped his scientific
journey and what he sees are the main current challenges in the field.

A thermodynamic description of porous media must handle the size- and
shape-dependence of media properties, in particular on the nano-scale. Such
dependencies are typically due to the presence of immiscible phases, contact areas
and contact lines. We propose a way to obtain average densities. We argue that the
average densities of the porous medium obey the Gibbs equation. From the Gibbs
equation and the balance equations, we then derive the entropy production in the
standard way, for transport of multi-phase fluids in a non-deformable, porous medium
exposed to differences in boundary pressures, temperatures, and chemical potentials.

Nonuniqueness of hydrodynamic dispersion revealed using fast 4D synchrotron x-ray
imaging

Experimental and field studies reported a significant discrepancy between the cleanup
and contamination time scales, while its cause is not yet addressed. Using
high-resolution fast synchrotron x-ray computed tomography, we characterized the
solute transport in a fully saturated sand packing for both contamination and
cleanup processes at similar hydrodynamic conditions. The discrepancy in the time
scales has been demonstrated by the nonuniqueness of hydrodynamic dispersion
coefficient versus injection rate (Péclet number). This nonuniqueness has been
attributed to the concentration-dependent diffusion coefficient during the cocurrent
and countercurrent advection and diffusion, present in contamination and cleanup
processes.
