2 PhD scholarships Mixing in Porous Media
Spanish National Research Council
The Institute of Environmental Assessment and Water Research (IDAEA) is a Severo-Ochoa center of excellence. The institute is devoted to the study of the human footprint on the biosphere. Its scientific personnel have a strong multidisciplinary nature and is formed by researchers from engineering, physics, environmental, geological, and chemical sciences. IDAEA is organized in two departments, Geoscience and Environmental Chemistry. The team forms part of the Geosciences department and focuses on the quantitative understanding and upscaling of processes in permeable natural and engineered media. IDAEA forms part of the Spanish National Research Council (CSIC), which is the largest public research organization in Spain, and the third largest in Europe.

The Spanish National Research Council (IDAEA-CSIC, Barcelona, Spain) is offering 2 PhD scholarships on mixing in porous media. The positions are funded by the European Union Marie Skłodowska-Curie Innovative Training Network CoPerMix (grant number 956457) on Control, Prediction and Learning in Mixing Processes within the Horizon 2020 Programme of the European Commission. CoPerMix is a consortium of high profile universities, research institutions and companies located in France, Spain, Germany, Switzerland, Belgium, Italy and the UK, and will train 15 PhD students in total (Early Stage Researcher, ESR). The objective of the network is to develop a unified vision, numerical tools, and experimental techniques allowing the description and the quantification of mixing processes in complex flows, such as turbulent atmospheric or oceanic flows and those encountered in geological, granular and biological media. The PhD student will be based at Barcelona at the Institute of Environmental Assessment and Water Research (IDAEA-CSIC).
- Eligibility Criteria
In order to be eligible, the applicant must fulfill the following criteria at the time of recruitment:
- Mobility: At the time of recruitment, the applicant must not have resided or carried out his/her main activity (work, studies, etc.) in the country of the host organization for more than 12 months in the 3 years immediately prior to his/her recruitment. Compulsory national service and/or short stays such as holidays are not taken into account.
- Qualifications and research experience: The applicant must fulfill the requirements defined for Early Stage Researchers (ESRs): ESRs are researchers who, at the time of recruitment, have NOT yet been awarded the doctorate degree and are in the first 4 years (full-time equivalent) of his/her research career.
- Project 1
The objective of project 1 is to determine how the heterogeneity of porous medium affects convective instabilities, which is important to understand the behavior of geophysical fluids systems (e.g., geothermal groundwater systems, CO2 storage) and industrial applications (e.g., heat conduction in metallic foams). The methodology is based on high resolution numerical simulations to assess the relation between heterogeneous permeability fields and scalar distribution patterns, fluid deformation, convective velocity structure, and mixing efficiency. The simulations will be complemented with experiments carried in the laboratories of EAWAG (Zurich, Switzerland) and the Université Libre de Bruxelles (Brussels, Belgium). This will allow developing a theoretical framework to assess the performance of the systems in terms of upscaled parameters, and the feedback between reactions and instabilities.
- Project 2
While the local Darcy scale flow and transport processes are based on Darcy equation, and the advection-dispersion equation and extensions thereof, large-scale mixing and transport processes in geological media are a result of the synergetic action of local scale mass transfer processes and the spatial heterogeneity inherent to natural and engineered porous media. Despite its importance, little is known on the impact of realistic medium architecture and heterogeneity distributions as well as (velocity-dependent) local scale dispersion on large scale mixing dynamics. The combination of geostatistical and stratigraphic information with novel stochastic approaches to large scale transport, and an original lamellar mixing framework, will lead to a new understanding of mixing and dispersion processes in geological media.
- Formal requirements
Applicants should hold an MSc degree with good grades and have good English skills. As criteria for the assessment of qualifications, emphasis will also be laid on relevant work experience and previous publications (if any).
- Background of the successful candidate
- Master degree in physics, hydrogeology, geophysics, civil engineering, environmental physics, soil physics, engineering sciences, or a related discipline.
- Knowledge and skills in quantitative research.
- Skills in programming and scientific software.
- Experience in theory driven research with a clear view for applications.
- Interest in collaborative multi-disciplinary research.
- The ability to communicate verbally and in written form in English.
- Terms of Employment
The successful candidate will receive an attractive salary in accordance with the MSCA regulations for early stage researchers. The exact salary will be confirmed upon appointment and is dependent on the country correction factor (to allow for the difference in cost of living in different EU Member States). The salary includes a living allowance, a mobility allowance and a family allowance (if married). The guaranteed PhD funding is for 36 months. The target starting date is 1 May 2021.
