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…

Experimental study of diffusiophoresis in a cellular flow
Florence Raynal, Menghua Zhao, Romain Volk
In this article, we study experimentally the dispersion of colloids in a two-dimensional, time independent, Rayleigh-Bénard flow in the presence of salt gradients. Due to the addi…

Lagrangian flow statistics in experimental homogeneous isotropic turbulence
Cheng Wang, Sander G. Huisman, Thomas Basset +2
We report on Lagrangian flow statistics from experimental measurements of homogeneous isotropic turbulence. The investigated flow is driven by 12 impellers inside an icosahedral vo…
