中文摘要:
      基于二维水动力模型,在仅考虑潮流作用条件下,通过计算欧拉余流和拉格朗日余流并结合粒子追踪方法研究了辽宁大连—朝鲜龙渊郡连线北侧的北黄海北部海域的潮余流结构和粒子运移的趋势。结果表明:欧拉余流和拉格朗日余流流速整体较小,呈现由南向北的流向,但在獐子岛及长山群岛的附近岛屿和朝鲜半岛沿岸的海域欧拉余流和拉格朗日余流流速较大。对比粒子追踪计算的结果与欧拉余流和拉格朗日余流的结果表明,流向与粒子运移路径基本一致。该海湾的余流及粒子运动规律特点对辽东半岛东岸及朝鲜半岛西侧海域的排污及污染控制有重要的借鉴意义。

英文摘要:
      Based on two-dimensional hydrodynamic model and by taking only the tidal current action into account, the structure of tidal residual currents and the trend of particle migration in the northern part of the North Yellow Sea, which lies on the north of the line from Dalian of Liaoning Province to Longyuan County of North Korea, are studied through calculating the Euler residual current and the Lagrangian residual current and by means of particle tracking method. The results show that both the Euler residual current and the Lagrangian residual current are generally small in flow speed and flow from south to north, while in the waters near the Zhangzi Island and the Changshan Islands and in the coastal waters of Korean Peninsula the two residual currents are both larger in flow speed. By comparing with the results from particle tracking calculations, the flow directions of the two tidal residual currents are basically coincidence with the particle migration path. The regulation and characteristics of the tidal residual current flowing and the particle migrating in the study area have important reference significance for the sewage discharge and pollution control in the waters along the eastern coast of Liaodong Peninsula and the western side of Korean Peninsula. 
