The control of alumina support textural properties is a very important task in the framework of innovative catalytic material manufacturing. Mass transport in the porous medium is strongly affected by the micro-structure and could decrease  the impregnation efficiency of the active phase and the resulting catalytic activity.

In the context of complex fluid process development (bio-process, water treatment, material synthesis, plastic recycling), a thesis is suggested in order to study and model the local shear distribution in mixing unit for Reynolds numbers in between 2000 <Re<20000.

Recycling of PET polymer through chemical recycling routes has attracted a great deal of interest in recent years, to cope with plastics streams not handled by classical industrial PET mechanical recycling routes.

Biofuels as well as bio-based chemicals production represent a major transition to reduce our dependence on fossil resources.

Numerical simulation is essential to model flow in porous media and in particular to study underground storages of CO2 or H2. It indeed allows one to test different scenarii by simulating coupled physical mechanisms stemming from various domains (geology, geochemistry, flow and soil mechanics...)

Automotive industry is moving fast to offer hybrid and full electric vehicles in order to reduce the greenhouse gas emissions and pollutants.  Then electric motors may be considered as one of the most important device in the next emerging vehicle architecture.

With the reduction of hydrocarbon resources and increasingly stringent standards to deal with the problem of climate change, the development of clean-up internal combustion engines constitutes a major technical challenge. The use of hydrogen is considered a promising alternative for vehicles. Two main options are possible.

Among IFPEN applications, finding the optimal configuration of the inputs of a model leading to the best admissible performance appears in the design of complex systems such as electric motors or floating wind turbines.

Reinforcement Learning (RL) has been successfully applied to a number of problems, such as robotic control, task scheduling, and telecommunications.

Electrification of vehicles and improved efficiency of internal combustion engines (ICE) are the main levers to reduce greenhouse gas emissions. The second priority of the French strategy for the deployment of low-carbon hydrogen is the development of renewable hydrogen for use in fuel cells or for combustion in a spark-ignition engine (SIE).

The performance of simulators has a direct impact both on the quality of the simulation results and on the study of a wide variety of scientific hypotheses.

The drop in production costs of distributed energy production systems and electrochemical storage systems coupled with the evolution of regulations make it possible to build local energy management operations.
