| 摘 要： | 试验证明设掺气槽后消能作用增加主要表现在：增加泄流沿程消能效果，降低挑流出口流速系数 值，挑距缩短，增加空中扩散消能作用，挑流水舌入池尺度加大，入池水流的能量集度减小。并首次提出了设掺气槽后消能作用增强的计算公式。

| Abstract: | The experimental results have shown that the aerators play an important part in increasing energy diasipation. They can increase energy dissipation of flow in the channel, reduce the value of velocity coefficient in the deflector bucket and the jet trajectory length; they can also increase energy dissipation of jet flow in the air and diffusion length of the jet falling into the pool, as well as reduce the energy intensity of flow falling into the pool. On the basis of experiments the equations estimating the energy dissipation effect of the aerators on the outlet structure were obtained. |
