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…

Dynamic stall of a hydrofoil with tubercles in surface gravity waves
Guillaume Ricard, Gunnar Jacobi, Daniele Fiscaletti +1
The interaction of an object with an unsteady flow is non-trivial and is still far from being fully understood. When an airfoil or hydrofoil, for example, undergoes time-dependent…
