| Abstract: |
| In this study, we construct one 2-dimensional tidal simulation, using an unstructured Finite Volume Coastal Ocean Model (FVCOM). In the 2D model, we simulated the tidal turbines with the additional bottom drag, which was calculated from the relationship of the bottom friction dissipation and the rated rotor efficiency of the tidal energy turbine, in the element where the tidal turbines reside. This study analyzed the effect of the Tidal turbine to the hydrodynamic environment, and calculated the amount of the extractable tidal energy resource at Guishan Hangmen channel, considering the rotor wake effect. |
| 中文摘要: |
| 本文利用FVCOM数值模式以舟山群岛海域的龟山航门水道为例，建立二维潮汐、潮流模型，利用增加模型中部分网格的底摩擦系数来模拟潮流能发电机对潮流能的抽取。其中额外增加的底摩擦系数根据潮流能底摩擦耗散公式与潮流能发电机的额定转子效率（即潮流能发电机抽取潮流能的效率）之间的关系确定。本文利用数值结果分析了潮流能发电机阵列对水动力场的影响,在考虑发电机尾流作用下，结合Farm法计算得出了龟山航门水道的潮流能理论可开发量。 |
