Simulation of Concentration Distribution due to Waste-Water Discharging into the Deep Water Area in Qiantangjiang River

摘要: 从立面二维非恒定流体动力学方程出发,应用κ-ε湍流模式计算流场,再用准三维的浓度对流-扩散方程,即考虑了侧向扩散的立面二维浓度控制方程,模拟了钱塘江江心6个竖管排污在潮流作用下近区浓度场,其结果和实际观测值基本吻合。Abstract: The flow field is simulated by using 2-D vertical unsteady fluid dynamic equations,in which a κ-ε urbulent model is employed.Based on the flow field,concentration distribution is computed by solving a quasi-3-D concentration equation in the near area of 6-point waste-water discharged in the deep water in Qiantangjiang river.Compared of the surveyed fields,the computational results are reasonable.
