In autumn, the Alpine massif is regularly subjected to warm and wet Mediterranean airstream generated by the eastward progress of a cold front associated to a pressure...

The new industrial superconductors using high critical temperature compounds offer new possibilities for superconducting magnetism. Indeed they allow higher magnetic...

Outdoor sound propagation is strongly influenced by the environment. The geometry, such as topography and the presence of obstacles, alters the sound through...

Travail issu d'une collaboration entre le laboratoire d'aérodynamique du CNAM Paris (situé sur le site IAT de Saint-Cyr l'Ecole) et le service ORL de l'hôpital saint Michel de...

The purpose of this work is to model by digital simulation the mechanical strength of automotive seat flanges obtained by half-blanking of high yield strength steel...

Numerical verification of industrial codes, such as those developed at EDF R&D, is required to estimate the precision and the quality of computed results, even...

Outdoor sound prediction is both a societal concern and a scientific issue. This paper deals with numerical simulations of micrometeorological (temperature and wind)...

We use the mesoscale meteorological model Meso-NH, taking the drag force of trees into account under stable, unstable and neutral conditions in a real case study....

Des analyses par thermographie pulsée conduites sur des données expérimentales et simulées sont présentées. Ces méthodes sont appliquées à des données issues d'une...

A growing number of applications such as micro-machining of electronical components need high average power in a various range of wavelengths (infrared at 1030 nm,...

This manuscript deals with the numerical and experimental characterisation of the behaviour of marine current turbines. In the experimental part, trials were run at...

The design of fan systems at Valeo Thermal Systems and the prediction of their aerodynamic performances rely mainly on virtual development methods, i.e....

The work of this thesis is about the numerical modeling and simulation of the propagation of acoustic waves in the presence of a flow. The model used for these studies...

The application of MQL or dry machining in mass production becomes more and more accepted. Dry (MQL) machining is a very efficient solution to reduce the usage of...

Numerical simulation for Resin Transfer Molding (RTM) manufacturing process is attempted by using the eXtended Finite Element Method (XFEM) combined with the level set...

The design of flexible lifting bodies in the naval industry, such as propelleror rudders, create some new design problems. This thesis proposes a numerical method...

In an industrial context, and in particular in the automotive industry, the systems' reliability has to be efficiently demonstrated, in a quick and cheap way. In PSA,...

This numerical investigation of an advanced Gurson–Tvergaard–Needleman (GTN) model is an extension of the original work of Ben Bettaieb et al. (2011). The model has...

Reductive extraction is one of the most promising pyroprocess for processing spentnuclear fuel. The extraction of elements from a molten salt to a liquid metal occurs...
