Their stability and eventual breakdown influence wake dynamics, mixing processes, and overall flow performance. This seminar presents two recent studies exploring vortex stability and vortex breakdown.<br>\r\nPart I – Short-wave instability of a helical vortex<br>\r\nThe first part of the seminar discusses the short-wave instability of a helical vortex generated by a rotating blade. Combining experimental dye visualisations, numerical simulations, and theoretical analysis, the study identifies displacement perturbations whose wavelengths are small relative to the helix radius and pitch but may remain large compared with the vortex core size. Stability analysis based on experimentally measured vortex profiles reveals broad bands of unstable wavenumbers for several vortex bending modes. These results differ from predictions of existing theories for short-wave vortex instability. Similar instability modes are also observed in arrays of straight vortices, indicating that the phenomenon is not related to vortex curvature. A theoretical examination of the dispersion relation of Kelvin modes for the measured vortex profiles uncovers a previously unidentified family of modes associated with the specific vorticity distribution. Their non-resonant interaction through the strain field provides a plausible explanation for the experimentally observed instability features.<br>\r\nPart II – Two-phase wing-tip vortex breakdown<br>\r\nThe second part presents the discovery of a new flow feature observed in the wake of a rectangular wing in water: the breakdown of the wing-tip vortex triggered by the injection of air into the vortex core downstream of the wing. Experiments show that, for certain combinations of Reynolds number and angle of attack, a stationary air bubble becomes trapped within the vortex core at a finite distance behind the wing and can persist for several minutes even after the air injection is stopped. Under different conditions, the bubble may drift upstream or downstream, or it may disintegrate immediately. Measurements of bubble properties and vortex characteristics reveal that the breakdown behaviour depends primarily on the vortex circulation and on the axial flow component within the core. The formation of a stable breakdown bubble occurs only when a velocity excess relative to the free stream is present.<br>\r\nThe two studies highlight new mechanisms governing the stability and transformation of vortical flows, offering insight into the dynamics of vortex instabilities and vortex-core modifications in fluid systems.<br>\r\n<br>\r\n<br>\r\n<strong>Biography</strong><br>\r\nThomas Leweke graduated from RWTH Aachen University in Germany in 1990 with a “Diplom” (Master) in Physics. He completed his PhD in 1994 at the Université de Provence in Marseille, on the experimental study and modelling of bluff-body wakes. After a post-doctoral stay at Cornell University on vortex instabilities, he joined the IRPHE institute in Marseille in 1996 as a CNRS Researcher and became a Senior Researcher in 2007. His research focusses on the experimental study of fundamental aspects of fluid mechanics, especially in vortex dynamics and fluid-structure interactions, with relevance to applications.

In contrast to zero-sum games—which do not always capture conflict, even between two players—harmonic games may exhibit highly non-convex equilibrium configurations. In particular, if the game’s ambient dimension is odd, we show that the set of totally mixed Nash equilibria is a (typically non-convex) real algebraic variety of dimension at least one, which extends all the way to the boundary of the game’s strategy space. Despite the difficulties incurred by this complicated equilibrium structure, we provide an extrapolation-based variant of “follow-the-regularized-leader” (FTRL) which converges to Nash equilibrium with order-optimal regret guarantees: O(1) in self-play, and O( sqrt(T) ) against arbitrary play.<br>\r\n<br>\r\n<br>\r\n<strong>Biography</strong><br>\r\nDavide Legacci is a PhD candidate in Computer Science at Université Grenoble Alpes, CNRS and Inria, within the GHOST team, supervised by Panayotis Mertikopoulos and Bary S.

Janelidze, L. Márki and W. Tholen in 2002, generalizes that of abelian category, and captures the homological properties that the categories of groups, associative algebras, Lie algebras and cocommutative Hopf algebras over a field have in common. Internal structures behave surprisingly well in semi-abelian categories. For example, any internal reflexive graph admits at most one internal category structure, and the categories of internal categories and internal groupoids are isomorphic. Moreover, the category of internal groupoids is equivalent to the category of internal crossed modules. The notion of internal crossed module in any semi-abelian category was introduced by G. Janelidze in 2003, and recovers in particular the classical notion of crossed module of groups. The fact that the category of internal groupoids in a semi-abelian category is itself semi-abelian implies that also the category of internal n-fold groupoids is well-behaved.<br>\r\n <br>\r\nIn this talk, I will prove that the full subcategory of internal n-groupoids in a semi-abelian category is a Birkhoff subcategory of the category of internal n-fold groupoids, and provide a simple description of the corresponding reflection for n=2. In the abelian context, the internal n-groupoids yield a torsion-free subcategory of the category of internal n-fold groupoids, and it is possible to characterize (higher) central extensions and compute generalized Hopf formulae for homology. <br>\r\n <br>\r\nPart of this talk is based on joint work with Marino Gran<br>\r\n </p>", "image_description": "", "creation_date": "2026-03-25T12:18:18", "last_modification_date": "2026-03-25T12:25:27", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "MA B1 504", "url_place_and_room": "https://plan.epfl.ch/?room==MA%20B1%20504", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "Nadja Egner, UC Louvain", "organizer": "Markus Kirolos", "contact": "Maroussia Schaffner", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 3, "fr_label": "Entrée libre", "en_label": "Free" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/120179/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/1/?format=api", "https://memento.epfl.ch/api/v1/mementos/5/?format=api", "https://memento.epfl.ch/api/v1/mementos/9/?format=api", "https://memento.epfl.ch/api/v1/mementos/7/?format=api", "https://memento.epfl.ch/api/v1/mementos/6/?format=api" ] }, { "id": 71448, "title": "Topological properties of rough fluids and plasmas", "slug": "topological-properties-of-rough-fluids-and-plasmas", "event_url": "https://memento.epfl.ch/event/topological-properties-of-rough-fluids-and-plasmas", "visual_url": "https://memento.epfl.ch/image/32796/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/32796/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/32796/max-size.jpg", "lang": "en", "start_date": "2026-04-24", "end_date": "2026-04-24", "start_time": "14:15:00", "end_time": null, "description": "<p>Abstract:<br>\r\nAs anticipated by Onsager's conjecture, low-regularity solutions of the Euler equations exhibit greater flexibility than classical solutions.

The key tool is a novel implementation of convex integration that preserves the topology of the streamlines throughout the iteration.
