Faraday waves covered by a viscoelastic sheet
Hanna Pot, Bram Christiaens, Willem van de Water
The hydroelastic response of free floating viscoelastic covers is measured using Faraday waves on the surface of a vertically oscillated fluid layer. We systematically vary the thi…

First observation of the Josephson-Anderson relation in experiments on hydrodynamic drag
Nicola Savelli, Ali R Khojasteh, Abel-John Buchner +2
We verify a recent prediction (Eq. 3.50 in G. L. Eyink, Phys. Rev. X 11, 031054 (2021)) for the drag on an object moving through a fluid. In this prediction the velocity field is d…

Linear response of turbulence
H. E. Cekli, G. Bertens, W van de Water
We study the response of wind tunnel turbulence to perturbations using an active grid. We compare our findings to Kraichnan's linear response result $R(k,Ï_d) = \exp(-k^2 \: Ï_d^…
