摘 要: 分散作用是污染物主要运移特性之一,逆流分散运动受到水流流速的影响,逆流分散范围将受到流速的限制。目前考虑纵向分散作用的水质模型计算中忽略了逆流流速的作用,认为逆流分散范围无限远,这是不合理的。从逆流分散运移特性分析,探讨了逆流分散的边界条件,并应用于求解咸潮一维扩散方程的解析解,提高了污染物逆流分散计算的准确性。 Scattering is on e of main transportion characteristics of pollutants. Backward dispersion is influenced by flow velocity. The scope of backward dispersion is limited by velocity. Existing water quality model calculation method neglects the impact of backward velocity,it is unreasonable. In this paper the bondage conditions of backward dispersion are taken into consideration from backward dispersion transportation characteristic, and the accuracy of backward dispersion calculation of pollutants is improved.
