摘要
利用不规则三角形网格和分步杂交方法建立了西涌湾及邻近海域的二维变边界潮流数值模型 ,并在此基础上建立了相应海域的拉格朗日余流模型 ,对拟建排污口标识质点的运移轨迹进行跟踪。通过计算分析 ,给出了西涌湾及邻近海域的水交换活跃区和滞缓区 ,并为拟设排污口进行了优化选择。
A two-dimension varied boundary tidal current numerical model of Xiyong Bay and its adjacent sea area is developed by using the irregular triangle grids and the split steps finite element method.According to this,Lagrangian Residual current model of the sea area is modeled to trace the track of the labelled particles released from the planed discharge position.Through numerical computation,the active area and static one of the water exchange in the Xiyong Bay and the sea area nearby are described,and moreover,the optimise design of the planed discharge position is chosen.
