    The Laboratory of Fluid Mechanics and Acoustics (CNRS, Ecole Centrale de Lyon) is seeking a highly qualified candidate for a post-doctoral research fellowship regarding the development of synthetic turbulent inflow conditions for high-fidelity Lattice Boltzmann simulations. Such methods have been developed in the context of NavierStokes approaches at the laboratory. The objective is here to adapt and extend those methods in the context of LBM, with a particular attention paid to the generation of noise.The successful candidate will be in charge of the development and implementation of turbulent inflow conditions in an in-house LB code (written in C++). Validations and evaluations will be carried-out on cases of increasing complexity: isolated boundary layer, compressor cascade and a fan configuration.

    The aim of the present project is to develop an efficient solid wall treatment for LBM, including turbulent wall models. Several issues will be addressed, among which:• interpolation methods used within the Immersed-Boundary Method (IBM) or Cartesian meshes framework for solid boundary treatment [1-2]• use of a turbulent wall model in conjunction with immersed solid boundaries [3]• reconstruction of the density distribution functions of LBM at boundaries nodeswithin this framework (accuracy, mass conservation, ...)• reconstruction of macroscopic quantities on the solid surface for post-processing purposes (eg. calculation of aerodynamic forces applied on an airfoil)• extension to moving/deforming solid boundaries

    Multiple PhD positions are available at Eindhoven University of Technology in the field of turbulence research.

    This thesis will focus on internal tidal waves (at diurnal and semi-diurnal frequencies), and may further extend to other type of ocean internal wave (e.g. near-inertial waves).

    The postdoc position is offered within Team CaliSto at Inria Sophia Antipolis Méditerranée. The team is working on the stochastic modeling applied to single-phase and multiphase flows through complex stochastic differential equations. This is done in collaborations with researchers that share interest in environmental applications (including meteorologists, hydro-physicists, physicists specialized in turbulence and two-phase flows modeling).

    Le projet de R&D SLITHER (financement région AURA) s’inscrit dans une problématique persistante en maintenance aéronautique : le décapage automatisé complet des aéronefs. Aujourd’hui, le décapage des surfaces des aéronefs n’est toujours pas pleinement automatisable du fait de l’impossibilité de gérer la variabilité des couches de peinture, des formes des appareils et de la difficulté d’accès à certaines zones en environnement complexe, en particulier dans les ailes des avions.

    The objective of the present project is to develop numerical tools to identify near-field fluctuations that optimally radiate sound, both in subsonic jets and in the flow around an airfoil. The study programme is based on theoretical concepts from linear instability analysis and from aeroacoustics.

    The main objective of this project is to establish on a robust scientific basis the existence of tipping points due to nonlinear feedbacks in the atmospheric circulation. This is a key question, because of the role of the atmosphere in the global climate through the transport of momentum, energy and water vapor across latitudes, but also because it acts as a forcing for other components of the climate system, such as the ocean and vegetation. The project focuses on the circulation of the tropical atmosphere, which has the potential for large-scale reorganization and could affect climate worldwide through its coupling with the tropical ocean.

    The aim of the internship will be to analyze data, compute space-time statistics, and answer questions pertaining to the underlying physics, such as the link between large and small-scale statistics at different ages of the flow.

    La morphologie des dunes est classiquement définie par une hauteur et une longueur d’onde (Ashley, 1990). Toutefois, la morphologie des formes dunaires peut être complexe, et des formes secondaires se surimposent couramment à la forme principale, rendant l’extraction de l’information morphologique plus complexe.Nous proposons d’évaluer les différentes longueurs d’onde présentes dans des formes dunaires, grâce à la notion d’ « échelle » (ceci peut être aussi vu comme une taille d’une structure élémentaire). Cette approche est courante dans le domaine des écoulements turbulents (voir par exemple Sagaut et Cambon 2018, ou les cours classiques de turbulence). En effet, un champ turbulent présente par définition une multitude d’échelles (ou, tourbillons). Il est alors d’usage de filtrer ce champ à une échelle spécifique pour analyser ensuite différentes grandeurs physiques (énergie, dissymétrie etc..) à chaque échelle.
