摘要
为研究掌握波浪能传播规律,通过构建波浪能由离岸向近岸传播的简易模型,利用WW3(WAVEWATCHⅢ)模式对波浪能传播规律展开数值模拟分析。结果表明:波浪能并非水深越深能量越大,且风向对离岸波浪能大小影响较大,对近岸影响较小;对福建海岸,若盛行风向与海岸近乎垂直,波力电站适宜建在离岸距离较近的水深为20 m左右海域,相关结论对波浪能的开发利用具有一定实用价值。
To study and understand the propagation regulation of wave energy,we constructed a simple model of wave energy propagation from offshore to nearshore to perform simulation analysis of the wave energy propagation regulation,using the WAVEWATCH-Ⅲ(WW3)numerical model.The relevant conclusions have certain practical value for wave energy development and utilization.The results show that wave energy does not increase with increasing water depth.The wind direction has a great influence on the offshore wave energy but little influence on the nearshore wave energy.For the coast of Fujian,if the prevailing wind direction is nearly perpendicular to the coast,it is suitable to build a wave power station in the sea with about 20 m depth near the shore.
