摘要
采用不规则三角形网格的分步杂交法 ,建立渤海湾海域二维变边界潮流数值模型 ,重现该海域潮波及潮流的时空分布 ,计算得到M2 分潮和K1 分潮的同潮时线与等振幅线、潮流椭圆及不同时刻潮流场分布。
Using the split steps finite element method,the varied-boundary two-dimensional numerical model of the tidal current in the Bohai Bay is constructed.The tidal wave and tidal current distributing pattern of the Bay is analyzed.Cotidal chart and iso-amplitude curves for M 2 constituent,Cotidal chart and iso-amplitude curves for K 1 constituent,distribution of tidal current ellipses as well as computed tidal current field has been received by calculation.The result of calculation is conformable to the field observations.
