Linear modelling of flame instability
Jeudi 19 Mars, 11h
Flame dynamics involve many effects (hydrodynamics, acoustics, thermal expansion, reaction and more), and they are known to display unstable behaviour in a large variety of configurations. These (...)
Reconstruction de la directivité de la voix humaine à l’aide d’antennes de microphones de géométrie arbitraire
Jeudi 26 Février, 11h
La directivité d’une source sonore caractérise la dépendance angulaire du champ rayonné. Au cours des vingt dernières années, de nombreux projets de recherche se sont intéressé à la directivité de (...)
Coupled oscillations, microstreaming, and other bubble-related phenomena
Jeudi 5 Février 2026 - ECL (amphi 3, bât. W1)
Acoustic bubbles are known to allow a contactless and localized action on surrounding bodies, through a direct push-pull action or by the softer effect of microstreaming it generates in its (...)
Turbulence in dilute polymer solutions away from solid boundaries
Jeudi 22 janvier 2026 - 11h, Amphi 1bis, bât. W1, ECL
It is well known that when minute amounts of polymer are added into a Newtonian fluid the resulting fluid solution displays stark differences compared to a Newtonian fluid. One particularly (...)
Characterizing large-scale intermittency in stratified turbulence: advanced coarse-graining and neural network approaches
Jeudi 15 Janvier, 14h INSA Lyon (amphithéâtre Marc Seguin)
We investigate the dynamics and dimensional complexity of stratified turbulent flows governed by the Boussinesq equations, combining analytical and data-driven modeling. Stratified turbulence, as (...)
One Cascade, Many Scales: A Unified Model of Low-Frequency Plasma Turbulence
Reporté
A central problem in space and astrophysical plasmas is to understand how a weakly collisional medium is heated by turbulence. In such systems, the cascade is not free to develop in the manner (...)
Experimental surface waves : turbulence, shock waves and interaction with a hydrofoil
Jeudi 8 janvier 2026, 11h, Amphi 3, bât. W1, ECL
Wave dynamics at the surface of the ocean are a key phenomenon to understand the exchanges between the ocean and the atmosphere. However, many wave phenomena are still far from being fully (...)
