| 摘要: |
| 对基于流体动力学理论设计的注气式人工上升流提升装置进行了千岛湖湖试, 并比较了不同注气结构(环形、十字形), 不同注气孔径(24 孔、400 孔)下的提升效果。试验结果显示, 十字形注气装置效果优于环形注气装置, 并且24 孔的提升效果优于400 孔。该次湖试验证了注气人工上升流理论的正确性和可行性, 并为下一步的理论和试验研究提供了试验依据。 |

| Artificial upwelling device test in the Qiandao Lake |
|
|
| Abstract: |
| In this paper, artificial upwelling devices designed based on the fluid dynamic theory were tested in the Qiandao Lake. The upwelling efficiency was compared between air injection instruments with different shapes (circle or cross), and different air injection diameters (2 mm or 0.5 mm, which was respected to 24 or 400 holes, respectively). The result showed that the most efficient one was the cross one with diameter of 2 mm. In conclusion, this lake test result has validated the artificial upwelling theory and feasibility, and it can provide useful references for further research. |
