Hydrodynamic force on a small squirmer moving with a time-dependent velocity at small Reynolds numbers
T. Redaelli, F. Candelier, R. Mehaddi +2
We calculate the hydrodynamic force on a small spherical, unsteady squirmer moving with a time-dependent velocity in a fluid at rest, taking into account convective and unsteady fl…
Zonal jets experiments in the gas giants' zonostrophic regime
Daphné Lemasquerier, Benjamin Favier, Michael Le Bars
Intense east-west winds called zonal jets are observed in the atmospheres of Jupiter and Saturn and extend in their deep interior. We present experimental results from a fully thre…
Morphology and dynamical stability of self-gravitating vortices: Numerical simulations
Steven Rendon Restrepo, Pierre Barge
Theoretical and numerical studies have shown that large-scale vortices in Protoplanetary discs can result from various hydrodynamical instabilities. Once produced, such vortices ca…
Localized layers of turbulence in stratified horizontally sheared Poiseuille flow
Joris Labarbe, Patrice Le Gal, Uwe Harlander +2
This article presents a numerical analysis of the instability developing in horizontally sheared Poiseuille flow, when stratification extends along the vertical direction. Our stud…
Indentation of an elastic disk on a circular supporting ring
Tristan Suzanne, Julien Deschamps, Marc Georgelin +1
Thin elastic two-dimensionnal systems under compressive stresses may relieve part of their stretching energy by developing out of plane undulations. We investigate experimentally a…
Spontaneous suppression of inverse energy cascade in instability-driven 2D turbulence
Adrian van Kan, Benjamin Favier, Keith Julien +1
Instabilities of fluid flows often generate turbulence. Using extensive direct numerical simulations, we study two-dimensional turbulence driven by a wavenumber-localised instabili…
