Monsoon‐Frontal Interactions Drive Cyclone Biparjoy's Wake Recovery in the Arabian Sea

Geophysical Research Letters
Cyclone‐generated cold wakes enhance productivity and impact local air‐sea interaction, paths and intensities of subsequent storms in the region. However, in‐situ observations of recovery across such wakes are rare.

Wake Recovery Enhancement with Helix Active Wake Control: Vortex Structures in a Porous Disk Wake Observed in PIV Experiments

Journal of Physics: Conference Series
Abstract Power losses at waked turbines due to the energy extraction of upstream turbines from the flow pose a major risk to the economic feasibility of wind farms. Helix active wake control has proven its potential to mitigate these wake-induced power losses by accelerating the recovery of the individual turbine wakes.

Wind turbine wake dynamics subjected to atmospheric gravity waves: a measurement-driven large-eddy simulation study [PDF]

Wind Energy Science
Atmospheric gravity waves (AGWs) are large-scale wave-like flow structures commonly generated when atmospheric flows are vertically perturbed by topographical features or meteorological phenomena.

Dynamics of floating-wind-turbine wakes in a wind tunnel setup [PDF]

Wind Energy Science
The wake of a laboratory-scale floating offshore wind turbine model is investigated under prescribed sinusoidal surge, sway, roll, pitch, and yaw motions using large-eddy simulations coupled to an actuator-line model.

Unsteady Loading on a Tidal Turbine Due to the Turbulent Wake of an Upstream Turbine Interacting with a Seabed Ridge

Energies
Tidal sites can present uneven seabed bathymetry features that induce favourable or adverse pressure gradients and are sources of turbulence, and so are likely to affect the operation, performance, and wake recovery dynamics of deployed tidal-stream ...

Large mammal recovery in the wake of human population decline

Journal of Applied Ecology
Abstract Human population growth has long driven biodiversity loss. Yet, some places are now experiencing depopulation, which can facilitate the recovery of large mammals.

Wake Recovery of Vertical-Axis Wind Turbines: Effects of Rotor Solidity and Reynolds Number

Applied Sciences
The wake evolution of vertical-axis wind turbines (VAWTs) plays a critical role in turbine-array performance, yet the wake variations associated with rotor geometry, operating condition, and Reynolds-number-related factors remain insufficiently ...
