Nonequilibrium scalings of turbulent wakes [PDF]
Physical Review Fluids, 2016 Nonequilibrium turbulent wake scalings are not the preserve of irregular (fractal-like/multiscale) plates but appear to be universal, as they also hold for regular plates over a very substantial downstream ...

Observation of Offshore Wind Farm Wakes by Spaceborne Synthetic Aperture Radar [PDF]
Journal of Geodesy and Geoinformation Science, 2021 In this paper, studies on offshore wind farm wakes observed by spaceborne synthetic aperture radar (SAR) are reviewed mainly based on our previous research. Particularly, we focus on investigating wind wakes and tidal current wakes observed by spaceborne

Interaction of turbulent kinetic energy and coherent motion in the near field of the cylinder wake
Mechanics & Industry, 2023 The far aim of the study is to experimentally assess the exchange of turbulent kinetic energy (TKE) of a wake behind a cylinder, as a function of the upstream flow.

Energies, 2021 Wakes appearing downstream of disturbances on the surface of a water flow in a concave open channel were examined experimentally. The investigated channel geometry was similar to the liquid lithium target in DONES (Demonstration fusion power plant ...

In the Wake of the Wake of the Wake [PDF]
Wasafiri, 2021 My favourite Simon Armitage poem, ‘Homecoming’, begins, ‘Think, two things on their own and both at once’, and tells, in brief, through juxtapositions of imagery, the story of a subject, ‘you’, a l...

Three-dimensional structure of wind turbine wakes as measured by scanning lidar [PDF]
Atmospheric Measurement Techniques, 2017 The lower wind speeds and increased turbulence that are characteristic of turbine wakes have considerable consequences on large wind farms: turbines located downwind generate less power and experience increased turbulent loads. The structures of wakes

An Analytical Model for Wind Turbine Wakes under Pressure Gradient
Energies, 2022 In this study, we present an analytical modeling framework for wind turbine wakes under an arbitrary pressure gradient imposed by the base flow. The model is based on the conservation of the streamwise momentum and self-similarity of the wake velocity ...

Journal of Marine Science and Engineering, 2022 Two modal decomposition techniques, including proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), were used to identify the wake patterns past single and two crossing cylinders in 60° and 90° arrangements with gap ratio G = 4. The

Identifying the Origin of Turbulence Using Convolutional Neural Networks
Fluids, 2022 Though turbulence is often thought to have universal behavior regardless of origin, it may be possible to distinguish between the types of turbulence generated by different sources.
