Numerical methods and optimization

Driven by environmental and energy frugality challenges, there is growing interest in vehicle fuel efficiency and a reduction in the impact of mobility. While the promotion of alternative transport modes to cars remains the principal lever for change, much can still be done in terms of road traffic management. An IFPEN team worked on this subject as part of a thesis in collaboration with Gipsa-lab...

Inside porous materials, physico-chemical phenomena such as matter transport, catalytic reactions and capillary effects are strongly influenced by the geometry of the pore networks, i.e., the degree of porosity, the distribution of pore sizes and their connectivity. (....) IFPEN and Saint Gobain Research Provence decided to tackle the problem differently, by exploring a new numerical approach...

Transport of molecules within porous structures that adsorb on the surfaces plays an important role in numerous contexts and very different applications. These include pollutant transport in soils, industrial catalytic conversion and purification processes, and chromatographic techniques...

Anchor lines, the majority of which are carbon steel cables, are essential components for the stability of offshore floating structures, such as those supporting wind turbines. To overcome the risk of breakage during service, redundant lines are generally incorporated at the design stage, which adds significantly to the cost...

To address the challenges of the energy transition, the subsurface has an important role to play, both in terms of providing resources and offering storage solutions. (...) Numerical models can help gain a better understanding of the subsurface with a view to its long-term management and optimal use. Developed for a number of years now at IFPEN, initially for the petroleum industry, such models cover scales ranging from the sedimentary basin to the reservoir...
