Numerical methods and optimization

THESIS BY PAULINE SIMONNIN

Proposing innovative technological products often requires recourse to simulation approaches in order to boost our capacity to evaluate original concepts. This is particularly true in the field of

Floating wind turbine technologies , such as those co-developed by SBM and IFPEN a , are designed to optimize the recovery of offshore wind energy . Optimization solutions are currently being sought

Natural underground fractures in rocks provide fluids with preferential flow pathways. The resulting global permeability is exploited for energy production ( geothermal energy and oil and gas recovery

IFPEN has been carrying out research in the field of floating wind turbines for a number of years, developing, for this purpose, the DeepLines Wind TM simulation tool , in partnership with Principia

In the field of numerical simulation , a sufficiently accurate representation of the data associated with physical models requires, in general, a very large numerical grid that, despite existing

Multiphase mixture (gas and liquid) flow simulation in porous media has a variety of applications in the field of geosciences a but also in the fields of engineering and chemical processes . In

Numerical simulation is a strategic tool , complementary to experimental studies, used to gain a precise understanding of complex physical phenomena . With many simulation tools a , performance

Vehicle approval standards require increasingly high levels of engine performance (low fuel consumption and low emissions) over a broad working range. It is for this reason that new engine

Gasoline direct injection engines emit soot particles during rapid transients . This still poorly understood phenomenon is taken into account during new WLTCs a , aimed at more accurately reproducing
