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。Abstract : the distribution of cooling air which is in the grille - brick of the inner combustion hot air stove has been simulated with three dimension turbulent mathematical model so as to find a method which is used to improve the distribution of cooling air in hot air stove. the influence of differential horizontal plates on the distribution of cooling air is discussed. the results show that original big circle round field of flow in the pillar - cavity is changed into full one - way field of flow and edges gas flow, at the same time, is increased by horizontal plates. there is a different function with horizontal plates and vertical plates. to make the uniform distribution of cooling air in the hot air stove, it is necessary that horizontal plates and vertical plates are used in a combined way
文摘:應用紊流三維數學模型模擬內燃式熱風爐內冷風在格子磚柱中的分佈，尋求改善其分佈的途徑.討論了加設不同布置的水平導流板對氣流分佈的影響.模擬結果表明，在支柱空腔內加設水平導流板改變了原有大迴旋流場，使迴旋流變成大面積的單向流.通過在支柱空腔內加設水平導流板可以發展邊緣氣流，這恰好與加設豎直導流板的作用相反，水平導流板和豎直導流板的結合使用有望實現冷風在格子磚柱中的均勻分佈Device model experiments of shaft - well two - direction tubular pumping station
