DESCRIPTION:Agathe Schmider\, LadHyX\, École Polytechnique\nAbstract: Fl
 ow-structure interactions play a crucial role in engineering\, enabling bo
 th energy harvesting and passive flow control. Cylindrical structures can 
 exhibit vortex-induced vibrations (VIV)\, where periodic vortex shedding d
 rives oscillations. While VIV can threaten structural stability\, it also 
 offers potential for energy extraction. To explore this\, we developed an 
 oscillating cylinder system with tunable mechanical properties to study en
 ergy harvesting efficiency. In contrast\, kirigami-based structures levera
 ge smart shape-shifting to passively adapt to the flow. Inspired by paper 
 cutting\, these sheets deform into steady-state shapes dictated by their c
 utting patterns\, functioning as poro-elastic membranes. Their fluid-struc
 ture coupling enables flow control by modifying wake dynamics.\nThese two 
 examples of fluid-structure interactions provide insights into harnessing 
 flow-induced motions for engineering applications.\n\nBio: Agathe Schmider
  has worked for several years as an engineer in the aerospace and renewabl
 e energy sectors before turning to research. She is currently a postdoctor
 al researcher with Sophie Ramananarivo and Pascal Hémon at LadHyX (École
  Polytechnique\, Palaiseau\, France)\, following the completion of her PhD
  in fluid mechanics in 2023 at Université de Poitiers (France). Her resea
 rch focuses on fluid-structure interactions at moderate Reynolds numbers a
 nd their applications in engineering.
