Instabilities in tidal turbine wakes [PDF]
Proceedings of the European Wave and Tidal Energy Conference, 2023 We report on the observation of vortex instabilities in the wake of a tidal turbine undergoing harmonic unsteady axial inflow (e.g. due to surface waves). The work was carried out using unsteady RANS (URANS) modelling using the open-source CFD software OpenFOAM, using the `pimpleDyMFoam' solver.
