| 摘 要： | 广东汕头高新技术产业园区西区向汕头牛田洋排放污水,为科学评价污水排放的影响,需进行污染扩散计算.根据牛田洋肚大口小的地形特点和排污方案论证计算的需要,本模型采用正交曲线网格,网格既能贴牛田洋弯曲边界,又能克服计算域网格疏密悬殊的问题.该污染扩散模型,通过验证计算,最大潮位误差0.06m,潮位、流速过程与实测基本一致,模型采用的糙率对牛田洋是适宜的,建立的污染扩散数学模型较真实地模拟了牛田洋附近水域的水流情况和污染扩散仿规律.

| Abstract: | The discharge sewage from Western part of High - tech Industrial Zone to Niutianyang Shantou, Guangdong Province needs scientific evaluation and calculation for its pollution dispersion. According to the topographic feature of belly - big but mouth - small and the needs of calculating demonstration, a model is designed in a way of orthogonal curvilinear grid, which not only docks the both bending borders ofNiutianyang, but also overcomes the grid spacing problem in computational domain. Through the computation, the maximum tide level error is within 0. 06m and both tidal level and flow rate are consistent with the measured process of the designed model. The rough - rate adopted by the model is appropriate and the pollution dispersion model established has factually simulated the Niutianyang water flow conditions and pollution dispersion simulation rules. |
