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。It is studied that the formation mechanism of taylor bubble and its control method in gas - liquid two - phase flow, which affects the pressure balance and mechanical driving efficiency in the flow of petroleum engineering. experiments show that the formation of taylor bubble in gas - liquid two - phase flow is due to the intensive congregation and amalgamation of small bubbles driven by void fraction waves and that the highly turbulent flow is able to restrain this formation. thus, the flow regime transition may be checked by increasing the flow turbulence and controlling the disturbed frequency
對大管徑氣-液兩相流動中嚴重影響壓力平衡與機械驅動效率的段塞流生成機制和控制方法進行了研究，實驗證明段塞流的形成是由於空隙率波的大幅度增長使氣泡高度集中，並形成聚並所致。強湍流運動可以抑制taylor泡的形成。因此，通過強化湍流或控制擾動頻率可以對氣泡聚並起明顯的抑制作用。The characteristic of the forming of shock wave in the tube and the influence of the shock wave intensity on cooling effect was also analyzed in working time. the reason why the cooling efficiency was lower in low rotate speed and has no change in high rotate speed was revealed
