Mobility and reactivity of native H2 in a West Australian basin

It is now established that molecular hydrogen (H2) exists naturally on the planet in the form of diffuse or continuous emanations. However, many questions remain unanswered as to its origin, formation mechanisms and real potential for exploitation.

Implicit solvers with time-step coresolution and warm start for evolution problems in geosciences

The numerical discretization of physical models representing evolutionary problems in many fields leads to nonlinear algebraic systems of very large dimensions. The process of solving these systems, which must be carried out robustly and rapidly at each time-step in order to increase software efficiency, comes up against a number of obstacles.

Bifunctional catalysis for the valorization of saturated fatty compounds

Producing renewable fuels and chemicals from biomass is mandatory in the fight against climate change as well as land and sea pollution. Fatty acids, derived from the lipid fraction of biomass, are oleochemical molecules of choice for the manufacture of biodegradable surfactants, cosmetics, lubricants and polymers.

Real-Time Data-Driven Modeling of Road Traffic Pollutant Emissions and Atmospheric Concentrations at an Urban Scale

The importance of air quality cannot be underestimated as it represents a major public health issue: today, nearly 91% of the global population is exposed to air pollution levels exceeding the exposure thresholds set by the WHO. This thesis lies at the intersection of three scientific domains: numerical modeling, air quality, and deep learning.

Réduction de modèle pour un problème non-linéaire avec interfaces multiples : application à la modélisation de câbles d'ancrage

The employment of high fidelity simulators in industrial application still remain nowadays limited by their computational cost, in particular for the optimization of structure design and reliability assessment. To overcome this situation, several reduced order modeling (ROM) techniques have been developed.

Development of a PTV technique for 3D3C characterization of liquid films in direct liquid cooling of electrical systems

Increasing our scientific and technical knowledge is a vital lever for improving energy systems and reducing our environmental footprint. With this in mind, we propose to develop a technique for simultaneously characterizing the thickness of a liquid film, the flow velocity field within it and that in the surrounding air.

Machine learning applied to the characterization of fluids used in electric propulsion chains.

This thesis is part of the field of the evolution of thermal management of electric propulsion chains, a key element for improving the performance of electric vehicles in terms of power density. Automobile manufacturers are moving towards the use of a “single fluid” for managing the cooling and lubrication of the propulsion chain.
