摘    要:采用曲线网格技术,将ECOMSED模式应用于胶州湾的潮流和污染物COD的稀释扩散研究,建主了一个三维保守污染物COD输运的对流扩散数值模型,对胶州湾M2分潮和COD污染状况进行了模拟。结果表明,胶州湾及其附近海域存在许多大小、强弱和旋转方向不同的余流涡;湾内COD浓度东部比西部高,湾口外的COD浓度等值线成舌状分布,向东伸展;余流和COD浓度垂向分布差异并不显。模拟结果与胶州湾的实测资料符合较好。

关 键 词:胶州湾  潮流  污染物  扩散  数值模拟  ECOMSED模式  余流

Abstract:Including the orthogonal curvilinear grid system, the model of ECOMSED was applied to simulate M 2 tide, tidal currents and the pollutant COD diffusion. Then, a 3-D model for conservative pollutant advection transport was made. The model results show that around the Jiaozhou Bay there are many residual current eddies differing in size, magnitude and rotation direction. The COD concentration in the east Jiaozhou Bay is higher than that in the west. The COD concentration isolines in the mouth of the Jiaozhou Bay are tongue-like distribution and stretch eastwards. The vertical distribution diversities of the residual current and the COD concentration are non-significant. The computed results match well with the observed ones in the Jiaozhou Bay.
Keywords:Residual current  Pollutant diffusion  Numerical simulation  Jiaozhou Bay
