| 摘 要： | 结合上海市污水治理二期工程，介绍了排海工程中扩散器水力计算的新方法，通过控制扩散器三通及喷头局部阻力系数，使各上升管出流量不均匀分配，根据伯努利能量方程组建立数学模型，用数学模型来计算扩放器上升管出流量和水头损失，并通过扩散器水力模型试验进行验证，结果表明，数学模型计算结果与物理模型实测值非常吻合。

| Abstract: | This paper presents a new method of hydraulic calculation on oceanic outfall diffuser used in Shanghai Sewage Project Stage 2. Through controlling the T-junction and nozzle's resistance coefficients,the unbalanced riser flow distribution has been achieved.Based on the energy approach,a mathematical model for predicting the riser flow distribution and headloss of diffuser has been developed.The predictions are in good agreement with the experimental results of the physical model. |
