量纲分析对污水近区初始稀释度变化规律的探讨

Discussion on the Variation Law of Initial Dilution in the Near Field with Dimensional Analysis Method

在上海合流污水二期工程白龙港排放口水力模型试验基础上,根据模型实验的大量数据,采用量纲分析方法对近区初始稀释度的变化规律进行了探讨,得出了描述该区域初始稀释度变化规律的半理论半经验公式,可为实际排海工程的设计提供依据。

Based on the hydraulic model test of the Shanghai Combined Sewerage Project Ⅱ, Bailong Gang Outfall Engineering, the variation law of the initial dilution in the near field was discussed with the dimensional analysis method through experimental data. The half-empirical and half-theoretical formula describing variation of the initial dilution in this zone was obtained. It can provide the basis for designing outfall engineering.
