-
摘要: 潮流能是一种海洋可再生能源，具有广阔的应用前景。通过数值模拟方法，对江苏沿海的潮流能分布进行估算。首先建立了江苏沿海平面二维潮流数学模型，并利用多次现场实测资料进行验证；基于数学模型计算结果，分析了江苏沿海的潮流场特征；其次，利用准调和分析方法对15 d潮流模拟结果进行调和分析得到6个分潮调和常数，并继而得到最大可能流速和潮流能流密度；最后，利用估算方法对海区的潮流能进行了估算。研究结果表明，江苏沿海燕尾港以南水域平均潮流能流密度相对较高，其中废黄河口附近海域、苏北辐射沙洲水道区域潮流能最为集中，平均能流密度最大值为700~1 200 W/m2，理论上具有较高的开发与应用价值。Abstract: The tidal current energy is a kind of marine renewable energy and has a vast range of prospects for making use of clean energy resources. The numerical simulation is used to assess the tidal current energy in the Jiangsu coast in this paper. The measured data are validated by a two-dimensional mathematical model for the tidal current along the Jiangsu coast. Based on the calculated results given by the mathematical model, the characteristics of the tidal current field along the Jiangsu coastal area are analyzed. 15 day tidal current simulation results are harmonized by use of a quasi-harmonic analysis method to calculate the harmonic constants of six tidal components, and then the maximum probable tidal velocity and the current density of the tidal current energy are obtained from the simulation calculations. Finally, the estimation methods are used to assess the tidal current energy in the key sea area. The simulated results show that there is a higher average tidal flow density in the south waters of the Yanweigang harbor, and within the waters the tidal current energy is mainly concentrating near the abandoned Yellow River mouth and in the waterway of the radiation bar in the north of Jiangsu Province, where the maximum value of the average energy current density is about 700~1 200 W/m2, which is highly valuable for development and utilization, as a new and clean energy.
