潮流中污染物离散的理论分析与应用

THE THEORETICAL ANALYSIS OF POLLUTANT DISPERSION IN TIDAL FLOW AND ITS APPLICATION

  • 摘要: 利用浓度矩法推导了纵向流速分布可分离为空间函数与时间函数相乘型式的二维潮汐流动中剪切离散系数的表达式,获得了对数流速分布下正弦式潮汐流离散系数随时间的变化过程,对离散与潮流特征的关系以及负离散问题进行了分析。最后将理论分析成果应用于珠江黄埔河段,获得了与实测资料相符的结果。

     

    Abstract: In this paper a formula is derived for shear dispersion coefficients of two dimensional tidal flow, the velocity distributions of which can be expressed by the product of a space-dependent function and a time-dependent function, by the method of concen-trational moment. The process of dispersion coefficients versus time is calculated in case of sine tidal flow with logarithmic velocity distribution. The relation of dispersion and features of tidal flow, and the phenomenon of negative dispersion are analyzed...
