电厂冷却水排放是电厂的一种副产品，会对沿岸环境造成严重影响。为了准确预测大亚湾核电站核污染物的输运过程，建立了一个三维水动力和温度模式，模拟了核电站核污染物向沿岸沃茨的输运过程。具体来说，我们使用的流速模型来定位拉格朗日相干结构（LCS）隐藏在海洋表面流。结果表明，CW的输运与模拟的LCS有很强的联系。LCS构成流体屏障，准确地划分CW传输的潜在途径。因此，从海岸模式的速度场LCS是一个非常有用的方式来监测和解释CW的传输。(C)2013爱思唯尔有限公司保留所有权利。
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. (C) 2013 Elsevier Ltd. All rights reserved.
