 ies.":Cocusse Marion : "2D turbulence under the full Coriolis force in a st
 ratified rotating fluid"\n\nThe traditional approximation\, which is widely
  used in geophysical fluid\n dynamics\, consists in neglecting the horizont
 al component of the \nplanetary angular velocity vector (i.e. the non-tradi
 tional component) \ncompared to the vertical one (i.e. the traditional comp
 onent). This is \njustified by the fact that vertical motions are usually w
 eak compared to\n horizontal motions for geophysical flows. However\, under
  certain \ncircumstances such as at low latitudes or for large vertical vel
 ocities\,\n the Coriolis force due to the non-traditional component of the 
 \nbackground rotation can become non-negligible. Here\, we investigate the 
 \nimpact of this non-traditional Coriolis force for different flows with \n
 DNS. First\, we examine a 2D Lamb-Oseen vortex and show that\, under weak \
 nstratification\, a critical layer appears\, and an instability accelerates
 \n the decay of the vortex.  We then consider forced 2D turbulence \ngenera
 ted through two distinct forcing: Lamb-Oseen vortices dipoles \nperiodicall
 y produced on the side of the domain\, and a random forcing in\n spectral s
 pace. We find that the non-traditional Coriolis force induces\n an anomalou
 s dissipation of energy\, thereby disrupting the classical \ninverse energy
  cascade characteristic of 2D turbulence.\n\n\n\nLe Dreff Julien : "Moving 
 backward to go faster: Diatom-inspired sliding reveals efficient modes of l
 ocomotion"\n\nAcross biological scales\, from sperm cells to whales\, locom
 otion \ncommonly relies on undulatory gaits\, in which traveling deformatio
 n \nwaves interact with the surrounding fluid to generate thrust opposite t
 o\n the direction of wave propagation. In viscous environments\, \nmicroorg
 anism locomotion is classically understood in terms of \nundulatory bending
  of slender filaments such as flagella\, with optimal \npropulsion achieved
  when the deformation wavelength is comparable to the\n swimmer length. Ins
 pired by diatom colonies\, we identify a \nfundamentally different swimming
  mechanism based on sliding between \nneighboring elements within a chain. 
 We show that sliding between \nstacked elongated cells generates internal s
 hear that drives propulsion \nopposite to classical undulatory swimming\, w
 hile achieving higher speeds\n and greater energetic efficiency. Remarkably
 \, optimal performance \noccurs at wavelengths much larger than the chain l
 ength and at cell \naspect ratios consistent with those observed in natural
  diatom colonies\,\n suggesting that hydrodynamic efficiency may constitute
  an evolutionary \nselective pressure in diatom chains. Together\, these re
 sults identify \nsliding as a previously overlooked mode of locomotion in m
 ulticellular \nassemblies.

 o the vibroacoustic of plates immersed in a heavy fluid and excited by a tu
 rbulent boundary layer\n\nAbstract:\nIn the marine sector\, controlling the
  self-noise and radiated noise of marine vehicles is a key challenge. The c
 haracterization of the vibro-acoustic response of these structures\, before
  production\, is necessary to ensure performance control. However\, the str
 uctures developed in this sector are large\, stiffened\, coupled to a heavy
  fluid and subject to turbulent flow\, making experimentation difficult\, c
 ostly and time-consuming. The work carried out investigates the possibility
  of overcoming these constraints by developing an approach based on similit
 ude theory. This theory enables two systems and their responses to be linke
 d by so-called similitude laws\, providing the conditions under which the r
 esponse of the full-scale system can be predicted by evaluating the respons
 e of a scaled-down system\, whose properties in terms of dimensions\, mater
 ial\, surrounding fluid and external loading are different. More specifical
 ly\, this research project focuses on the case of a planar panel\, stiffene
 d or unstiffened\, loaded by a heavy fluid and excited by a turbulent bound
 ary layer. The development of similitude laws reveals the conditions to be 
 met in order to obtain an accurate prediction of the desired response. The 
 similitude laws and conditions are first studied and verified numerically. 
 Next\, a measurement campaign is carried out to validate these laws for pan
 els excited by a turbulent boundary layer in air. This seminar presents the
  method and some of the results obtained during the three years of the proj
 ect.
