研究罗源湾潮汐、潮流及潮波的传播,对罗源湾的开发及海岸工程建设具有一定的实际意义。为系统地了解罗源湾的潮汐、潮流状况,采用不规则三角形网格的分步杂交法,建立罗源湾海域二维变边界潮流数值模型,通过计算得到同潮时线与等振幅线、潮流椭圆、潮致欧拉余流分布及不同时刻潮流场分布。该海湾海流具往复流性质,潮汐、潮流均属正规半日潮,最大流速发生在可门水道。 |

Numerical simulation of tidal current in Luoyuan Bay |
|
Abstract: |
For engineering purpose in Luoyuan Bay, tide and tidal current is studied. Using split step finite element method, the varied-boundary two-dimensional numerical model of the tidal current was constructed. The tidal current at different times and the Eulerian residual current were calculated, also the cotidal line, iso-amplitude curves and distribution of tidal current ellipses in the bay were given in this paper. In the bay, the gulf current is back-and-forth in wature, the tide and tidal current are normal M2 type with the maximum flow speed in Kemem Channel. |
