Internships and Career Opportunities

Key Description Responsibilities - Designing, developing, and implementing a novel microfluidic platform for the detection of nanoplastics (design, microfabrication, testing and validation). - Performing experiments in environmental/clinical settings (river water/biologic fluids samples). - Writing of protocols and support documentation, data analysis, interpretation and identification of technology limitations and troubleshooting. - Results’ presentation and publication. - Supporting lab’s organization.

Key Description The thesis will be conducted as part of several research projects already funded: ANR Biocid@Home (Biocides at home: emissions, potential exposure and reduction solutions, 2021 – 2025) and the Francilian Observatory in Urban Hydrology (OPUR). It will be based in particular on experimental data acquired on two sites instrumented respectively in a residential area near Arcachon and in a recent dense urban area near Paris.

Key Description The first scientific objective is to characterise the ways in which the public problem of indoor air and water quality and that of micropollutants have been elaborated and have gradually become public health and environmental issues requiring the intervention of public authorities, but often in a non-integrated manner. Secondly, we need to understand the relation in between: (a) the cognitive construction of the water and air quality issues and, (b) the choice of public policy instruments and their implementation by the public stakeholders (local, regional and national authorities). In these policies, there is in fact a question of multi-level governance, as actions and combinations of actions implemented at the scale of urban territories by local authorities may be very different. Finally, this research on the public policy instruments will have to take into account the way targeted beneficiaries 'receive' the various messages and injunctions resulting from the choice of instruments (Baldassare and Katz, 1992; Halkier 2001; Kim et al, 2019). How are incentives to change practices or use of technical systems appropriated (or suverted) by the various targeted audiences?

Key Description The growing popularity of 3D printing with cement-based materials is leading to an increasing need for simulation tools able to predict stability during printing as well as durability during service life. Development of simulation tools requires a good understanding of the behavior of cement-based materials from early-age to hardened state, including strong couplings between mechanical, hydraulic, thermal and chemical aspects. It also asks for modelling strategies regarding the printing process itself to correctly assess actions on the material during printing, both from the printer and surrounding environment like thermal and drying effects. Most existing models for 3D printing focus essentially on the mechanical aspect of the behavior and printability of the structure. Development of a fully coupled predicting modelling tool for 3D printing is by essence a multidisciplinary task, needing a good knowledge of printing process, behavior of cement-based materials, thermodynamics and mechanics of chemically active porous materials, and numerical simulations. To tackle this problem a collective expertise has been mobilized since 2021 by participation of five researchers from three different teams of Navier Laboratory in the framework of a PhD thesis, financially supported by Ecole des Ponts ParisTech.

Key Description This PhD project will focus on numerical modelling, taking into account thermo-hydro-mechanical (THM) couplings, to evaluate the ground-support interaction and to have reliable predictions of the overall energy performance over time. Different numerical simulations will be carried out to account for the uncertainties in the design of these structures, taking into account the variations in stratigraphy and the presence of heterogeneities along the tunnel. The impact of this type of geostructure on the surrounding building and the interaction with existing underground structures will also be investigated. Soil characterisation from tunnel excavation projects, such as the Grand Paris Express, will form the basis of the different scenarios. The objective of the second stage is to provide engineers with a simple tool for pre-design. This will be done on the basis of different scenarios that will allow to better take into account the uncertainties (based on the results obtained from the numerical simulations carried out in the second stage).

Key Description This present PhD offer entitled “Offshore wind turbine monopile foundation: experimental and numerical study of soil-structure interaction” has two main goals: - Study of offshore wind turbine’s scale model subjected to cyclic loading. This study will include the improvement of the cyclic test procedure with a load-controlled setup. A parametric study can be considered: loading characteristics, sand density index, monopile rigidity, etc. The subsidence cone formation around the monopile should be also evaluated. - Study and development of empirical laws predicting the displacement/rotation accumulation and the foundation stiffness evolution as a function of the cycles number. Simulation of permanent strains/displacements after first load cycle (as a basis for the usual cyclic extrapolation methods) should be considered. One possible approach is a 3D FE analysis of laterally loaded monopile and soil continuum with hypoplastic constitutive model. This work will be based on the cyclic test program conducted in Navier laboratory.

Key Description Characterization and modelling of different fluid transport mechanisms, encompassing diffusion, multiphase flow, and flow through preferential pathways such as fractures, necessitate investigation. This PhD project will investigate these phenomena through laboratory experiments on decimetric samples of low permeable rock representative of caprock conditions.

Key Description – effects of wave non-linearity, wave breaking and complex flow structure. This thesis aims to contribute to the highly dynamic development of offshore wind energy, in particular for fixed wind turbines (for water depths less than 50-60 m).

Key Description The first objective of the PhD is to develop a new numerical strategy for implementing such models, allowing for the advanced simulation of SMA-based systems in the dynamic regime. The second objective of the PhD is to propose a new topology optimization approach for SMAs. Thanks to this approach, the geometry of the damper could be designed to maximize its efficiency for a given quantity of material, before printing it.

Key Description The main objective of the present work is to investigate fine predictions of the flow through wind turbines farms, as a prospective step in a project. One distinguishes two types of applications: The ones linked to the estimate of the potential power which can be produced by a farm including the wake and blockage effects. These two effects might be particularly crucial for large offshore farms; & The ones related to the estimate of mechanical loads applied by the wind and turbulence on the turbines. This will impact the choice of the turbines, their maintenance and their lifetime.

Key Description Management of the scientific/experimental part of the research project "In-Depth Study of the Structural and Physicochemical Properties of Iron-Doped Carbon Dots in Physiological Media for Diagnostics", as main experimenter, under the direct supervision of the project director (Dr. Laura TRAPIELLA).

Key Description Edvance, owned by EDF and Framatome, is Nuclear Island EPCC (Engineering / Procurement / Construction / Commissioning) for EDF Group’s new nuclear reactors. The internship will take place within Structural and BIM teams. It is part of the activities related to the subject of EDF digital transformation and standardization of new nuclear. It is important to ensure uniqueness of data and continuity of information, this standardization approach will be made available on the EPR2 project. In this context, the objective of this internship is to study the interoperability between Allplan (BIM software) and ANSYS (Finite Elements software) through the export of project load cases, as well as to carry out monitoring and model control. This 3D processing by the centralization of information and this interoperability between BIM software and FEM calculation software will allow us both gains in model quality, financial efficiency and planning by all actors, throughout of the project life cycle.

Key Description Edvance, owned by EDF and Framatome, is Nuclear Island EPCC (Engineering / Procurement / Construction / Commissioning) for EDF Group’s new nuclear reactors. The internship will take place within Structural and BIM teams and will be focused on embedded parts (anchorages). Anchorages are all the items at the interface between civil works and mechanical and electrical disciplines. They represent thousands of elements for each Nuclear Island divided into several families (pre-embedded anchor plates, post-installed anchor plates, prestresses anchors, sleeves, frames, …). The aim the internship will be the optimization of the process managing the interface between the design of anchorages and BIM tools. It will include:

The automatic detection of the surrounding environment within BIM model.

The link with calculation tools and the generation of design reports.

The management of the configuration within the Product Lifecycle Management (PLM) tool.

Key Description Currently, French government has delegated the CO2 emission ”management” (e.g., setting their own CO2 emissions target for 2050) to the regions and, because of the lack of coordination between them, the global CO2 reduction target is very likely to be largely missed, hence a crucial need to introduce and design coordinated decentralized emission strategies. It turns out that the state-of-the art of the scientific literature is incomplete for at least 3 reasons: 1. It focuses on this type of problems but only at the level of the countries (see the problem of agreement for the Conferences of Parties); 2. The proposed solutions are often empirical and do not rely on key mathematical properties that would guarantee the players to effectively implement the agreements; 3. The socio-economic modeling problem for a region largely differs from that at the country level. The following internship project aims at modeling the complex relationships between local consumers, regions and national authority in this problem of designing efficient decarbonization plan/mechanisms.
