| 摘 要： | 本文建立了一个适合于潮汐流动中污染物排放的远区动态平面二维数值计算模型。该模型的计算特点是将流场和浓度场分开计算，即所谓“非耦合解”，运用有限节点法计算了流场，用改进的有限节点法计算了浓度场。该模型应用于长江大厂镇江段，其计算出的流场和该江段典型污染物Ｆ－的浓度场与实测一致，在此基础上，用设计潮计算了一个污水排江方案，确定了其影响范围

| Abstract: | A2 D depth averaged dynamic far field numerical model is developed for simulation a jet pollution into tidel flows, The mode character is that compute velocity and pollution concentration respectively, which is also called no pairing resolution. The velocity and pouution concentration distribution are computed by the finite node method and improved one. The model has been applied to Dacheng section of Changjing River, the velocity and polltution F - concentration distribution of computation are in accord with those of measurement on this basis, the reasonable pollution area for one plan of the wastewater of Dachang district discharging into Changjing River has been obtained by this model. |
