Instabilities in tidal turbine wakes
- Abstract:
-
We report on the observation of vortex instabilities in the wake of a tidal turbine undergoing axially oscillating inflow, using unsteady RANS simulations. Unsteady inflow causes the turbine blades to shed vorticity of time-varying strength into the wake, which in turn leads to a spatial variation in wake vortex strength, such that the vorticity of adjacent returning wake segments can differ. This spatial variation triggers the instability of tip vortices, the characteristics of which are sho...
