As an unwanted by-product in the power plants, cooling water (CW) discharge may induce harmful effects on the coastal environment. In this paper, to accurately predict the CW transport in the Daya Bay, China, we develop a three-dimensional hydrodynamic and temperature model to simulate the transport of the CW from nuclear power plant into coastal waters. Specifically, we use the flow velocity produced by the model to locate Lagrangian coherent structures (LCSs) hidden in ocean surface currents. Result show that the transport of the CW is quite strongly tied to the simulated LCSs. The LCSs constitute fluid barriers that accurately demarcate potential pathway for CW transport. Thus, LCSs in velocity fields from a coastal model is an extremely useful way to monitor and interpret the transport of CW.
作为发电厂的一种非期望副产品，冷却水（CW）排放可能对沿海环境产生有害影响。在本文中，为了准确预测中国大亚湾的 CW 输运，我们开发了一个三维水动力和温度模型来模拟从核电站到沿海水域的 CW 输运。具体来说，我们使用模型产生的流速来定位隐藏在海洋表面流中的拉格朗日相干结构（LCS）。结果表明，CW 的输运与模拟的 LCS 密切相关。LCS 构成了流体屏障，准确地标定了 CW 输运的潜在路径。因此，沿海模型速度场中的 LCS 是监测和解释 CW 输运的一种非常有用的方法。
