Research Associate - Non-invasive imaging of porous media with x-ray computed tomography
Forschungszentrum Jülich GmbH Research Associate (Postdoc) to help support and develop research on non-invasive imaging of porous media with XRCT.
2 PhD’s on UFI-NMR of complex fluids in stratified porous layers
Eindhoven University of Technology Job Description
The aim of this project is to study the ingress of complex fluids (inspired by water-based inks) into thin stratified porous media (modified paper sheets) and the resulting film formation. A recently developed UFI-NMR tool will be used for real-time visualization and quantification of the transport of fluid components into paper. The obtained results will be used to develop a predictive model describing the transport and film formation processes. The NMR studies will be supplemented by SEM and other experimental tools to analyze the structure of the porous substrates.
Paper sheets are thin stratified porous media: the top layer often differs from the bulk in structure (coatings) and chemical interaction with the ink particles (fixation agents). The particles dispersed in inks often form films on top of or close to the paper surface. Fundamental understanding of ink penetration into paper and the formation of the particle films can only be obtained when this process can be monitored fast (milliseconds) and with high resolution (several microns). Recently, a breakthrough NMR-imaging technique has been developed at the TU/e (UFI-NMR) allowing ultra-fast-imaging (UFI) of capillary action in thin, porous layers. This new technique offers the opportunity to systematically study uptake of complex fluids in thin stratified porous media.
The project builds on the results of previous PhD work: the development of the UFI-NMR method and its application to fluid transport. You will become a member of the group Transport in Permeable Media (TPM) of the Applied Physics department. You will work in close collaboration with Canon Production Printing and Covestro, enabling you to access the experimental facilities of these companies and allowing you to work with taylor-made models liquids.

PhD position on Fluid transport in fractured mudrocks
Heriot-Watt University Predicting the retention of hydrogen gas in the subsurface is a cross cutting issue with relevance to energy storage, hydrogen prospecting, and the disposal of radioactive wastes. Underground hydrogen storage (UHS) is a means of storing intermittent energy production from renewable energy sources, and retention of the hydrogen in the geological reservoir is crucial for the economic performance of the store. This project will focus on the Mercia Mudrock Group (MMG) which is currently being considered as a potential host rock for GDF and caprock for UHS. Prediction of hydrogen migration (carrying radionuclide) in such geologies is challenged by the complex architecture of fault-fracture systems and mechanical stratigraphy of the interbedded mudrock and evaporites of the MMG, together with the inherent challenges of modelling complex multi-scalar transport phenomena in geological media. Demonstrating an understanding of the fracture hosted (single and two phase) fluid flow and solute transport process will be integral to such assessments. This PhD project will help to reduce uncertainty in the characterisation of fault-fracture systems and fluid flow in the MMG.
This broad scope of this research involves the observational description of MMG fault-fracture systems from outcrops and cores including assessing the mechanical-stratigraphic controls on fracture network geometries, the measurement of single (and multi-phase) flow in fractures as a function of rock-fracture properties, effective stress, and fracture / stress field orientations as well as the measurement of adsorbing solute and fluid specific transport processes.
2-year Postdoc on Colloidal transport in unsaturated porous media: column experiments and microtomography imaging
CNRS - Institut des Sciences de la Terre d'Orléans We are looking for talented postdoctoral fellow to investigate two-phase flow colloidal transport in porous media using column experiments and X-ray microtomography imaging. Expected skills include flow and transport in porous media, physico-chemistry of interfaces, colloidal science, mathematical upscaling, Digital Rock Physics, microfluidics, and microtromography imaging. The position is part of the European Research Council-founded project COCONUT.
The COCONUT project (awarded with an ERC Consolidator grant) aims to investigate how colloidal particles control two-phase flow in geological porous media using a combined experimental-simulation multi-scale approach. The objective of this postdoctoral position is to monitor the transport of colloids and their impact on two-phase flow in three-dimensional naturally occurring and heterogeneous porous structures. Can we visualize in-situ the underlying processes using non-destructive high-resolution imaging to investigate clogged pores and the fluids distribution, morphology, and remobilization? We are looking for a talented postdoctoral fellow to join our team and develop millimetric to centimetric column experiments coupled with time-lapse X-Ray microtomography imaging (lab and synchrotron measurements).
The candidate will • Develop its own line of research, • Perform a comprehensive literature review on colloidal transport and two-phase flow in porous media, • Develop millimetric and centimetric column scale experiments to investigate two-phase flow and colloidal transport using time-lapse microtomography imaging (lab and synchrotron facilities), • Microfluidic experiments can be conducted for preliminary results, • Analyze the results with Digital Rock Physics and homogenized mathematical models, • Participate to the weekly group meeting, • Present the results at national and international conferences, and in high-ranked journals.
2-year PostDoc position: Modelling mechanical and chemical erosion in porous media
CNRS - Institut des Sciences de la Terre d'Orléans We are looking for a motivated postdoctoral fellow with a strong background in fluid dynamics and computational sciences. Expected skills include fluid dynamics, flow and transport in porous media, reactive transport, mathematical upscaling, and computational fluid dynamics (CFD). The candidate is familiar with programming languages including C++ and is motivated by code development. The position is part of the French National Agency for Research (ANR)-founded project PhysErosion.
The objective of this postdoctoral position is to model and decipher the complex feedback between hydrodynamics and mechanical-chemical erosion. The candidate will develop an efficient and robust simulator for predicting erosion – both mechanical and chemical – processes at different scales of interest over a wide range of flow, chemistry, and material conditions. The developments will rely on porousMedia4Foam, our in-house OpenFOAM-based package coupled with PHREEQC for geochemistry. This package is based on the concept of micro-continuum models, i.e. a unique mathematical formulation that can solve flow and transport problems in porous media at different scales of interest (e.g. pore-scale, continuum-scale, and hybrid-scale). It is particularly well-suited to model moving solid-free / porous interfaces when mechanical and chemical erosion occurs. A step-wise strategy will be adopted that focuses first on the modelling of chemical and mechanical erosion mechanisms in porous media fully saturated in water and then on chemical erosion in unsaturated systems, i.e. when gas and air fill the pores and a multiphase description is needed.
PhD Position on Geochemical Processes and Multiphase Flow in Porous Media
Forschungszentrum Jülich With the ongoing energy transition, the exploitation of the subsurface (e.g., for geothermal energy extraction, CO2 sequestration, H2 storage or even nuclear waste disposal) will increase.

In the ERC funded project Genies, we aim to fill current knowledge gaps related to mineral dissolution and crystallization processes involving gas and transport in porous media. In the PhD project, the PhD student will investigate coupled mineral dissolution and precipitation processes with gas generation. The methodologies employed include microfluidic experiments and macroscopic experiments combined with dynamic MRI imaging.

PhD offer at the University of Orléans– Prediction of concentration gradients generated in geological porous media using microfluidic devices
University of Orléans (France) The objective is to predict the magnitude and location of local concentration gradients that develop in geological porous media due to mineral reactions. These concentration gradients can further lead to diffusiophoresis of charged particles. Typically, salt gradients can be generated by the dissolution of solid calcium carbonate in water, producing different ions that migrate into the aqueous phase at different velocities due to specific diffusion coefficients. Thus, spontaneous electric fields arise to maintain the electroneutrality in the solution, which can lead to diffusiophoretic transport of particles (McDermott et al. 2012, fig 1.). We will use microfluidic devices to study dissolution mechanisms of calcite crystals in controlled conditions (Soulaine et al., 2017). The challenge will be (i) the measurement of dissolved species and pH using Raman spectroscopy., (ii) geo-electrical measurement during micromodel experiments to analyze the signature of carbonate dissolution. We will assess the species transport dynamics in the vicinity of a dissolving crystal. Experimental results will extend our OpenFOAM-based micro-continuum approach that simulates the dissolution of solid minerals at the pore-scale (Soulaine et al., 2017). In a second step, more complex reactive micromodels will be considered, like flow-through reactors (an assemblage of reactive grains, see Poonoosamy et al. 2020) to localize concentration gradients generated by dissolution/precipitation of carbonates for various porous media properties. The experiment coupled with micro-Raman spectroscopic techniques will allow a quantitative in situ assessment of mineralogical changes in porous media during reactive transport processes. From Raman spectra we will obtain the mineral composition and solute composition, thus providing new insights into hydro-geochemical coupling in porous media.

PhD position at CNRS on the physics of solute transport in brain micro-vascular networks
University of Rennes and Institute of Fluid Mechanics of Toulouse Blood microcirculation supplies neurons with oxygen and clears their neurotoxic waste through a dense capillary network connected to a tree-like network of arterioles and venules. This microvascular architecture results in highly heterogeneous blood flow and travel time distributions [Jes12,Sak14], whose consequences on brain pathophysiology begin to be uncovered. To explore this question, the University of Rennes and the Toulouse Institute for Fluid Mechanics have bridged together their expertise on the physics of transport in disordered media, e.g. [LeB08], and on cerebrovascular structure/function relationships, e.g. [Lor11]. This has lead to the first physics-based upscaling framework describing the dynamics of solute transport in brain microvascular networks [Goi21]. This new representation uses random network and dipole flow theories to derive a stochastic model for solute transport in microvascular networks. It predicts the appearance of critical regions under reduced perfusion, i.e. with insufficient oxygen or excessive waste, which may play a key role in the onset of Alzheimer’ disease. This advance opens new opportunities for understanding the physics of solute transport in the brain and its impact on neurovascular diseases. Based on this new modeling framework, the objective of this PhD project is to investigate how the spatial organization of arterioles/venules controls the appearance and growth of critical regions of reduced oxygenation and waste clearance.

Postdoctoral position (3 years) on subsurface hydrogen storage
Delft University of Technology The overarching aim of this project is to investigate how multi-scale and hierarchical geological heterogeneities impact transport, mixing, and chemical reactions during subsurface hydrogen storage in depleted gas reservoirs. The main approach will be to perform a comprehensive simulation study, complemented by laboratory experiments carried out in a collaborative project. Ultimately, the project aims to characterise the key characteristics of depleted gas reservoirs that are suitable candidates for subsurface hydrogen storage. To achieve this aim, the successful candidate will be designing multi-scale reservoir modelling and simulation studies and utilise the results to develop dimensionless numbers that allow us to quantify the amount of back-produced hydrogen from depleted gas reservoirs while accounting for geological heterogeneity, mixing of cushion gas and hydrogen, geochemical reactions, and well designs.
This interdisciplinary project will be carried out in close collaboration with the industry partner Shell, and will be based at the Department of Geoscience and Engineering at TU Delft. There it will bridge across the research conducted at the reservoir engineering section and applied geology section, benefitting from the department's wider research activities in subsurface storage, the DARSim Research Group, and the Energi Simulation Centre for Geoenergy.
Closing date for any applications is May 27 at 23:59 CEST.

Postdoctoral Researcher "Multi-Scale Modeling of Processes" (M/F): High-Energy Efficiency Biogas Purification System
IMT Nord Europe Missions: The STIMulE (Support for Interdisciplinary, Multi-institutional, and Exploratory Works) program aims to promote collaboration and bring together various skills to contribute to the development of Hauts-de-France and nurture future regional scientific excellence. The collaborative research project "PISCO" involving the CERI Energy and Environment of IMT Nord Europe and the TIMR UTC-ESCOM laboratory is part of the development of selective and energy-efficient CO2/CH4 separation technologies, which are essential for the complete valorization of biogas (CH4 and CO2). The ultimate goal of the PISCO project is to propose an industrially feasible intensified adsorber for CO2 separation. This project proposes the use of biosourced polybenzoxazine resins as precursors for the production of selective CO2 adsorbents. Objectives: The recruited person will be responsible for conducting research work for the PISCO project. These works will focus on the modeling of the biogas purification process (CO2/CH4 separation) at two levels of scale: 1. Systemic Scale: Physical models simulating the behavior of complex energy systems with various components (separation units, solar heating, photovoltaic sensors, thermal storage, etc.) will be implemented to globally optimize the energy efficiency of the purification process as well as its performance indicators (purity, productivity, recovery rate). 2. Component Scale: System optimization will guide the development of an operational intensification technique at the scale of the adsorber-exchanger unit using computational fluid dynamics (CFD) methods.
