The slat flow field of a multi-element airfoil is experimentally studied. Mean turbulence statistics and phase-locked data link shear layer structures to narrowband peaks in the surface pressure spectra. Most notably, a bulk cove oscillation related to shear layer flapping is found.

Dynamic domains of the Derviche Tourneur sodium experiment: Simulations of a spherical magnetized Couette flow
Author(s): E. J. Kaplan, H.-C. Nataf, and N. Schaeffer
A magnetized liquid sodium experiment and high-end numerical simulations are performed, both yielding similar magnetic signatures. Coherent flow structures are found to emerge from developed turbulence, some of which are related to linear instabilities of the mean flow.
