| 摘 要： | 研究了连续点源污染物在近区的垂向扩散规律。通过理论推导，得出垂向均匀混合距离和部分混合水深的函数关系式，用实际资料验证取得较好结果。该将成果用于改进传统的全场水深平均的二维计算模型，解决了传统模型计算点源污染带时，近区浓度场计算值偏小的缺点。用改进模型来计算浓度场不仅节约了计算时间，而且大大地提高了近区浓度的真实性。

| Abstract: | The mixing law of the continuous point source,in the nature flow,is studied.By the theoretical analysis,two equations are presented:one is the distance of the vertical homogeneous mixing,other is the part depth of homogeneous mixing.The equations are verified by the measured data,and the results are satisfied.Using above theory,the improved 2D numerical model is developed.The shortcoming of the original model in the near field,the calculated value lower than real value,is overcome.The prominent advantages are that the results are reliable, and the working time is decreased. |
