Challenges related to assessing underwater noise pollution and seismic risks generated by human activities in shallow water environments

Jeudi 30 Octobre, 11h, ECL (Bat W1, amphi 3)

Assessing the impact of human activities on the marine environment is a prerequisite for the authorization of offshore projects (EU directive). It is also a necessary step in the search for (...)

A self-consistent numerical model of internal wave-induced mean flow oscillations in polar geometry

Jeudi 16 Octobre, 11h, ECL (Bat W1, amphi 3)

Decades of observations of the Earth’s equatorial stratosphere reveal a regular oscillation where winds alternate between eastern and western directions. Similar phenomena have also been detected (...)

Oleg A. Godin (Naval Postgraduate School, Monterey)

Noise interferometry for passive remote sensing of the ocean

Jeudi 09 Octobre, 11h, ECL (Bat W1, amphi 3)

In a wide range of frequencies spanning from below 1 mHz to hundreds of kHz and encompassing acoustic, gravity, and infragravity waves, ocean waves create pressure fluctuations, which can be (...)

Surfactant dynamics at liquid-liquid interfaces under shear: experimental study of the kinematic condition

Jeudi 4 Septembre, 11h, Ecole Centrale de Lyon, (bâtiment W1, amphi 3)

Lubricant-infused surfaces (LIS) are engineered materials that incorporate a stable liquid-liquid interface between a trapped lubricant and a working fluid. This configuration is expected to (...)

Acoustique Planétaire: une nouvelle technique d’analyse pour les interactions surface-atmosphères dans le Système Solaire

Mardi 1er Juillet, 11h, Ecole Centrale de Lyon (salle B11, bât. H10)

Sur Terre, l’analyse quantitative des ondes acoustiques est souvent utilisée pour caractériser l’environnement atmosphérique. Les applications les plus notables sont (i) la caractérisation de divers (...)

Jacques Borée (ISAE-ENSMA)

Manipulation of dynamical properties of turbulent near wakes for drag reduction (Séminaire Labellisé MEGA)

Vendredi 27 Juin, 11h, Bâtiment W1, Salle 101, Ecole Centrale de Lyon

Drag reduction of ground vehicles is a major challenge due to increasing need for reducing energy consumption and air pollution. Flows around such bluff bodies are locally or massively separated. (...)

Jacques Magnaudet (IMFT)

From Leonardo to StabFem: the long story of path instability of rising bubbles made short (Séminaire Labellisé MEGA)

Vendredi 13 Juin, 11h, Amphi 1 (Bâtiment W1), Ecole Centrale de Lyon

In this talk I will review the most significant advances achieved over the last three decades in our understanding of the path instability phenomenon affecting millimeter-sized gas bubbles rising (...)

Houssem Kasbaoui (Arizona State University)

Modeling Particle-Laden Flows: A Unifying Framework for Point-Particle and Particle-Resolved Direct Numerical Simulations

Lundi 2 juin, 11h (salle René Michel, Bât. Omega, UCBL)

Turbulent flows laden with micron-sized particles are ubiquitous in industrial and environmental applications such as sediment transport in nature and pipelines, operation of aircrafts in dusty (...)

Manikandan Mathur (IIT Madras)

Simultaneous Generation and Scattering of Internal Waves by Bottom Topography

Mercredi 28 Mai, 14h30 (amphi 1, Bât. W1, ECL)

Bottom topography are known to profoundly impact internal wave activity in the ocean. Barotropic tides interact with bottom topography like continental shelves and deep ocean ridges to generate (...)

Chris Keylock (Loughborough U.)

Reduced dimensionality of turbulence dynamics using complex networks

Vendredi 23 Mai, 11h (amphi 1, Bât. W1, ECL)

Network analysis is a means to coarse-grain a system’s dynamics whilst also providing its own tools for analysis. In our recent work we have proposed designing such networks so that rather than (...)
