The benefits of speed regulation in urban areas are demonstrated in terms of air quality, fuel consumption and traffic flow

Urban speed limits are one of the solutions available to big cities to improve traffic flow, to raise air quality, to rein in noise and to improve road safety. The prospect of additional benefits by adapting this limitation in real time, depending on traffic density, led an IFPEN team to evaluate this approach as part of a thesis work.

Dual-porosity and dual-fracture model for fractured geothermal reservoir simulation

Geothermal energy production has been developing since the start of the 2000s, and it is becoming necessary to have access to more precise numerical models to simulate the various scenarios that may be encountered. A new model combining dual porosity and dual fracture is proposed.

SC8 - “Massively” accelerated windfarm simulation

In the field of wind energy, Large Eddy Simulations (LES) are widely used to gain a better understanding of wind flow within wind farms. On a wind farm scale, they are also used to establish analytical wake models, and are useful for studying the interactions between individual wind turbines as well as with the atmospheric boundary layer (ABL)...

SC7 - Variable speed limits: for more eco-friendly urban traffic management

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...

SC4 - New numerical approach for the characterization of virtual porous materials

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...

SC3 - Simulation of the adsorption/transport combination via a generalized lattice-boltzmann 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...

“From material to structure” modeling: the case of anchor cables for offshore wind, in corrosive environment

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...

Underground modeling: an essential step for the energy transition

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...
