Clever experiment documents multi-scale fluid dynamics
2017/9/4
University of Chicago physicists working in the nascent field of experimental vortex dynamics have, with unexpected help from a Sharpie marker, achieved the first measurements of an elusive but fundam...
Direct measurements of anisotropic energy transfers in a rotating turbulence experiment
Direct measurements anisotropic energy turbulence experiment
2011/9/5
We investigate experimentally the in uence of a background rotation on the energy transfers in decaying grid turbulence. The anisotropic energy ux density, F(r) = hu (u)2i, where u is the vector v...
Kinematic dynamo simulations of von Kármán flows: application to the VKS experiment
application to the VKS experiment von Karman flows
2011/8/31
The VKS experiment has evidenced dynamo action in a highly turbulent liquid sodium von Karman ow [R. Monchaux et al., Phys. Rev. Lett. 98, 044502 (2007)]. However, the existence and the onset of a d...
