摘要 河流的流动形态复杂,影响水质的因素较多。对河流污染物迁移扩散机理进行分析,提出将流管划分与有限体积法相结合的方法,利用流管求取河流流场,有限体积法求取污染物的扩散。将其应用到重庆城区段的二维水质模拟,全部计算和可视化都通过FORTRAN实现,取得较好效果。该方法简单、准确、高效,具有较好的工程意义。 The contamination transplant-diffuse mechanism in shallow river is analysed. FVM is applied to the stream tubes, according to mass conservation principle and established the 2-D finite volume model in the contamination concentration field (CCF). This method is applied to simulate water quality of some section of Yangtze River and Jialing River around Chongqing city, which is simple and effective.
