烟台、威海南部近岸海域物理自净能力研究——Ⅱ.拉格朗日余流模型

STUDY OF PHYSICAL SELF-PURIFICATION CAPABILITY IN OFFSHORE AREA SOUTH OF YANTAI AND WEIHAI——Ⅱ. THE LAGRANGIAN RESIDUAL CURRENT MODEL

在该海域潮流计算的基础上,利用有限元法建立了二维的拉格朗日余流模型,得出了威海及烟台南部海域的拉格朗日余流分布。跟踪了文登、乳山、海阳、莱阳近岸主要排污口的污水输运轨迹,为沿岸县市污水排放的选址提供理论依据。

Based on the computed tidal current field, using the finite element method, a two-dimensional Lagrangian residual current model is established. We obtained the Lagrangian residual current field in the offshore area south of Yantai and Weihai, tracked the labelled particles of pollutant sources located at Wendeng, Rushan, Haiyang and Laiyang. The results provide a theoretical basis for the coastal cities in the selection of sewage discharged locations.
