Wind–Wave Interaction for Strong Winds
Journal of Physical Oceanography, 2023Abstract In this paper, we revisit the problem of wind–wave interaction with emphasis on strong winds. For these events, it is assumed that nonlinearity is so large that the slope of the wind waves has reached a limiting steepness. Recent observations suggest that the drag decreases with wind in the strong wind speed regime.

Proceedings of the European Wave and Tidal Energy Conference
Wave Dragon wave-wind project Wave power is more consistent than wind-, solar- and tidal power. Wave is at the same time more predictable than wind and solar. The paper assesses the economic performance of the different wave energy converter (WEC) types and discusses the possibility for WECs to match the levelized cost of energy for offshore wind ...

Wave-induced velocities are the primary driving force for littoral sand transport. For this reason, a major component of the NSTS program was to measure wave associated velocity and elevation fluctuations. A description of the shoaling wave transformation is a necessary ingredient in the development of any sediment transport model.

The wind field over wind-waves
Journal of the Oceanographical Society of Japan, 1976The velocity fluctuations of wind over wind-waves in a wind tunnel are measured with a X-type hot-wire anemometer at some heights over the water surface.

Renewable energy is accepted as a key source for the future, not only for Turkey, but also for the world. This study investigates the potential for wind and wave power around the world and in Turkey, and provides an overview of the historical development of both energy resources.

Rhythmic and monotonously repetitive, but quite unpredictable in its details, the structure of the sea surface is an epitome of the natural world. Surface waves have been studied actively by mathematicians and physicists since the dawn of modern science.

Nature, 1924
IN a letter published in NATURE on August 19, 1920, p. 777, I said that, judging from appearances, wind-formed waves increased in length only when the waves were in a “breaking” condition, and it was suggested that the breaking crests, by imparting their momentum to the upper strata of the water, and so establishing a gradually increasing surface ...

The Physics of Fluids, 1970
A criterion proposed earlier for determining airflow separation from wind waves and a previously determined relationship between surface roughness and wind stress are herein correlated. The results indicate that the airflow boundary layer is developed due to the form drag provided by wavelets (surface roughness) superimposed on big waves.

The most apparent and usually the most important waves in the spectrum of waves at sea (see Figure 5.2) are those generated by the wind. Wind-generated waves are much more complex than the simple monochromatic waves considered to this point. We must briefly look into how these waves are generated by the wind and some of the important characteristics ...
