A vertically-Lagrangian, non-hydrostatic, multilayer model for multiscale free-surface flows
I will present a semi-discrete, multilayer set of equations describing the three-dimensional motion (...)

Turbulence in and out of equilibrium
Kolmogorov postulated in 1941 that the small scales of turbulent flows away from boundaries can be considered universal if the Reynolds number is (...)

Instabilities and Lagrangian Transport
In uniform stratification, a horizontally propagating, vertically bounded internal tide eventually gives up energy to subharmonics through triad resonant (...)

Multi-scale interactions in the atmosphere. Application to the prediction of heat waves and urban heat islands
The climate system is described by approaches focusing on Zonal jets, Waves and (...)

Des interactions fluide-structure dans le domaine du naval à la R&D dans le domaine des énergies marines renouvelables
Avec l’accroissement de la taille des navires marchands de type (...)

Nascent fractal scaling during flat plate boundary layer transition to turbulence
As a boundary layer developing on a smooth surface transitions from a laminar to a turbulent state, spatially (...)

Dynamique d’un système mixte convectif / stablement stratifié
De nombreux systèmes fluides s’organisent en une couche turbulente adjacente à une couche stratifiée stable, comme par exemple les (...)

Rare-Event triggered Transitions in aerodynamic bifurcation
The transitions between two states of a bistable system are investigated experimentally and analyzed in the framework of rare-event (...)

Breaking description in depth-averaged models
Depth-averaged models are one of the classic approaches for coastal wave description. Dispersive models of this type such as the fully nonlinear (...)

Pulsation dynamics in a gas-centered swirl coaxial injector
Gas-centered swirl coaxial (GCSC) injectors, in which a gaseous jet fragments an annular swirling liquid sheet, are used in the liquid (...)
