明流泄洪洞反弧段体型的研究

A research on bucket shapes in free level discharge tunnel

  • 摘要: 在对多种变曲率反弧曲线的比较分析后,进行了大小不等的单圆弧反弧和连续反弧曲线反弧面的水力特性试验和分析认为,在明流泄洪洞反孤段上,采用变曲率反弧曲线对减免反弧末端空蚀破坏的作用甚微,宜考虑采用较大半径的单圆弧反弧,并在实际运用中应避免中小流量的泄流工况。

     

    Abstract: Based on the comparison and analysis of several upcurved spilling section of free level discharge tunnel, their hydraulic character tests were carried out specially in hydraulic model. Test results revealed that if adopt curves with varied curvature, little effect of anti- cavitation can be gained, it is better to use single circular curve with larger radius for cavitation prevention.
