3 结语

本文以Delft 3D的Flow模块为基础，建立斋堂岛及其附近水域的三维水力学模型。通过TSE方法确定了水轮机阵列的布放位置，并将水轮机对流场的影响等效成为动量损失的方式并组成不同排列方式的阵列加入到水力学模型中，从而对流场进行仿真并研究阵列对潮流场所产生的影响。

仿真结果显示，在斋堂岛东南部水域放置一定规模的水平轴潮流能水轮机阵列将会对该区域的流场带来一定影响：阵列会对较大范围水域的水位带来一定改变，且影响程度随阵列中水轮机密度的减少而降低，其中最大水位改变不超过3 cm；对区域流速的影响随阵列中水轮机密度的增加而愈加显著，当密度较大时阵列所引起的流速下降在其尾流区域能够达到0.45 m/s，影响距离可延伸至其下游2 km处。
