A spatio-temporal random synthetic turbulent velocity field: The underlying Gaussian structure

Matthieu Chatelain, Júlia Domingues Lemos, Wandrille Ruffenach +5

We develop, simulate and extend an initial proposition by Chaves et al. concerning a random incompressible vector field able to reproduce key ingredients of three-dimensional turbu…

Convective regimes of internally heated steady thermal convection of temperature-dependent viscous fluid

Hisashi Okuda, Shin-ichi Takehiro, Stéphane Labrosse

We study dynamical regimes of thermal convection with temperature-dependent viscosity driven by homogeneous internal heating. Two-dimensional steady-state convective solutions with…

Droplet on a sugar fiber

Stéphane Dorbolo, Floriane Weyer, Alexandre Delory +2

The motion of a water droplet on a single vertical sugar fiber is analyzed. The fiber is positioned vertically, with the droplet placed at its pending end. If the capillary force e…

Spontaneous stochasticity and the Armstrong-Vicol passive scalar

W. Ruffenach, E. Simonnet, N. Valade

Spontaneous stochasticity refers to the emergence of intrinsic randomness in deterministic systems under singular limits, a phenomenon conjectured to be fundamental in turbulence.…

Disentangling discrete and continuous spectra of tidally forced internal waves in shear flow

Yohei Onuki, Antoine Venaille

Generation of internal waves driven by barotropic tides over seafloor topography is a central issue in developing mixing and wave drag parameterizations for ocean circulation model…

A toy model of turbulent shear flow using vortons

Wandrille Ruffenach, Lucas Fery, Bérengère Dubrulle

We introduce a novel toy model for shear flows, exploiting the spatial intermittency and the scale separation between large-scale flows and small-scale structures. The model is hig…
