A Wind-Wave Farm System With Self-Energy Storage and Smoothed Power Output
IEEE Access, 2016 This paper proposes a wind-wave farm system with a self-energy storage capability and a smoothed total power output. The fluctuating electrical power from wave is smoothed by utilizing the rotor inertias of the wind turbines as short-term energy storage ...

Revisiting wind wave growth with fully coupled direct numerical simulations [PDF]
Journal of Fluid Mechanics, 2022 We investigate wind wave growth by direct numerical simulations solving for the two-phase Navier–Stokes equations. We consider the ratio of the wave speed $c$ to the wind friction velocity $u_*$ from $c/u_*= 2$ to 8, i.e. in the slow to intermediate wave

Relationship between Large-Scale Variability of North Pacific Waves and El Niño-Southern Oscillation
Journal of Marine Science and Engineering, 2023 Ocean waves are crucial for driving various oceanic processes. In this study, the spatial and temporal distribution of significant wave height (SWH) in the North Pacific (NP) is analyzed using the 42-year ERA5 reanalysis dataset from European Centre for ...

A state-of-the-art review of the hybrid wind-wave energy converter
Progress in Energy, 2022 The urgent demand for energy structural reform and the limitations of single energy development have promoted the combination of wind energy and wave energy. A hybrid energy system means that two or more energy devices share the same foundation.

Wind speed and direction estimation from wave spectra using deep learning [PDF]
Atmospheric Measurement Techniques, 2022 High-frequency parts of ocean wave spectra are strongly coupled to the local wind. Measurements of ocean wave spectra can be used to estimate sea surface winds.

A time-localized response of wave growth process under turbulent winds [PDF]
Annales Geophysicae, 2007 Very short time series (with lengths of approximately 40 s or 5~7 wave periods) of wind velocity fluctuations and wave elevation were recorded simultaneously and investigated using the wavelet bispectral analysis.
