Abstract

Rough waves may be incurred by strong wind over ocean, and the wind field behind the wave fluctuates violently, which can induce extraordinary impacts on bridges, offshore structures and vessels. The severely interfered performances of wind flows near sea surface by two patterns of rough waves are studied via wind tunnel tests. The research results indicate that the apparent influential region by wave ranges from the wave crest to 15 times of wave height downwind horizontally and 4 times of wave height upward vertically. For different waveform, the difference in the approaching region is more obvious, and it fades away slowly with farther distance. Behind the wave, the wind velocity and direction fluctuate violently and remarkable non-Gaussian property can be detected. The observations may present reference for wind-resistant design of bridges and offshore platforms.
