( 2 ) a kind of computational method for the spiral water flow in the air core region of drop shaft was discussed and applied and the results agree the experimental data well. ( 3 ) the total ratio of energy dissipation in the drop shaft can reach 90 % and the energy dissipation in every region was discussed quantitatively
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。The exhaust gas spews out of the exhaust valve and enters into the muffler along the exhaust manifold before draining into the atmosphere from the tail pipe. this process yields wide band exhaust noise
發動機廢氣從排氣門高速沖出,沿著排氣歧管進入消聲器,最後從尾管排入大氣,在這一過程中產生了寬頻帶的排氣噪聲。Macromolecule oilproof liquild sealant is used for adhensive and seal of motor engines, cylinder botton, oil undeypan, steam inlet and outlet pipe, gear shifting box, and gas thread
高分子耐油液體密封膠,用於粘接和密封各種機動車輛發動機缸墊、油底盤墊、進排氣管墊和變速箱底盤墊等及各種管道螺絲的密封。It tell us : the abrasive capability of fly ash ; the similar calculation of ash erosion ; the calculation of ash erosion in the tube in turn and tube out of turn ; the reason of tube abrasion for gas flue ; the influence of air parameter for fly ash erosion ; the influence of changing temperature ; the influence of the flue gas composition, etc. next, it advances the solving measure ; reduce the flue gas velocity ; reduce the concentration of fly ash ; responsible construction : replace smooth tube with spiral tube ; use the new material of abrasion ; fuel desulfurization ; reduce so3 of flue gas ; raise flue gas temperature, making it up the dew point ; use the abrasion - resistance material to resist abrasion

氣流影響消聲器性能的主要原因是發動機排氣的高速脈動氣流再生噪聲,其次是這種氣流會沖擊消聲器的管路、殼體、隔板等聲學元件,進而激發振動輻射噪聲。Jarraud said that while greenhouse gas emissions in 2100 can ' t be predicted, " continued pollution at today ' s rate - or faster - presents several risks, especially a rise in sea - levels " as polar ice melts
雅羅說,盡管人類還無法預測到2100年全球的二氧化碳排放量,但是如果環境污染繼續以目前的速度(或者更快的速度)加劇,人類將會面臨若干威脅,其中最突出的威脅是海平面的升高,因為氣溫的升高,現在地球兩極的冰雪正在不斷融化。The results indicate that the flow velocity is lower and the pressure is high in majority of the step cylinder, the distinct variations of the flow field occur in the threshold of the step cylinder at the bottom and the abrupt transition sections, the holes in the inner and outer tubes and the exhaust hole
