近年來,為解決高水頭、大流量導流洞改建泄洪洞的技術難題,旋流式豎井泄洪洞逐漸成為研究熱點之一。但迄今為止,該技術尚未得到推廣應用,其主要原因在於人們對豎井螺旋水流運動特徵缺乏足夠的了解和深入的研究。The bulk of the mass is spread out, forcing stars to trace a spirograph - like rosette : an ellipse that does not close on itself but gets offset each time the star completes one revolution [ see box at right ]

本文通過試驗研究與理論分析對旋流式豎井泄洪洞應用於高水頭、大泄流量情況時存在的一些水力學問題進行了研究和探討,取得以下主要成果:一、結合小灣工程導流洞改建,對高水頭( 252m ) 、大泄流量( 1400m ~ 3 s )條件下旋流式豎井中的水流運動特徵進行了比較全面的測量,包括空腔形態、徑向流速分佈及井壁壓強等;二、提出了豎井空腔段螺旋水流水力計算方法,其計算結果與實測值吻合良好;三、利用試驗與計算結果,對旋流式豎井的消能機理進行了探討,對豎井各部分的消能能力有了總體認識;四、對豎井下部消力井的合理井深進行了優化試驗研究,發現消力井合理深度為0 . 9d左右;五、通過試驗研究,歸納出豎井水流總摻氣量估算方法,為導流洞排氣方案的設計提供了參考依據;六、在高水頭、大流量條件下,豎井空腔段下部流速很高,盡管水流螺旋運動引起的離心力可以確保井壁壓強保持正壓,但空化數依然較低,因此豎井的空化空蝕始終是工程界關注的重大問題。Spiral motion control and simulation of buoyancy - driven underwater vehicle
