针对我国波浪能开发受近海低波能密度海况限制的现状,提出一种具有喇叭状开口的聚波水道,利用其聚集波浪,提高水道内波能密度.定义聚波水道在中心线上的投影长度为特征尺度,采用Star-CCM+软件仿真与模型实验相结合的方法,研究特征尺度与入射波波长之比对增波效果的影响.对比分析表明,在收缩段入口与出口宽度一定条件下,入射波波长为特征尺度2倍时,聚波水道增波效果最佳,波高增幅达53.12%.相较于依托特殊地形的聚波方式,聚波水道不受地形限制,有助于提高波浪能发电装置在我国周边低波能密度海域的适用性.
In view of the current situation that wave development in our country can be limited by the low sea wave energy density in the offshore, a kind of polyphonic waterway with trumpet-like opening is proposed to gather the waves to enhance the wave energy density in the watercourse. Length of the feature scale, Star-CCM + software simulation and model experiments were used to study the influence of the ratio between the characteristic scale and the wavelength of incident wave on the effect of the waves.The comparative analysis shows that under certain conditions of inlet and outlet width of the contraction section, When the wavelength of incident wave is 2 times of the characteristic scale, the effect of increasing wave is the best, and the increase of wave height is 53.12% .Compared with the polyphonic wave method which relies on special terrain, the polyphonic waterway is not limited by the terrain, which helps to improve the wave energy Applicability of Power Plants to Low Intensity Waves in China.
