surface blowing
解釋
面吹法-
And the lightness and freshness and intoxication of the gentle air blowing here and there, yet scarcely rippling the surface of the lake.
一陣陣微風吹過，多麼輕飄，多麼清新，多麼令人陶醉，可是湖上卻並沒有吹起的漣漪。 -
Results show that the influence of mainstream reynolds numbers on heat transfer coefficience is little and the heat transfer coefficience raise with the increase of reynolds numbers. the influence of the position of holes on heat transfer coefficience is complex and correlate with the mainstream speed and the balde surface curvature. and the influence of blowing ratio on heat transfer coefficience is more great ( especially to stator ), and show a complex relation to mainstream reynolds number and the position of holes
實驗結果表明，不同孔位出流的換熱由於孔排下游表面來流速度及葉片表面曲率的不同而有不同的規律，而主流雷諾數對葉片表面特別是壓力面和前緣區域的換熱系數比的影響較小，吹風比對換熱系數影響較大（特別是導葉） ，並且隨氣膜孔位置和來流雷諾數的變化而情況復雜。 -
( 2 ) on the leading edge, the film cooling effectiveness at the zone immediately downstream of the cooling holes is affected by blowing ratio and mainstream reynolds number, while the effects are not important in the downstream zone far from the cooling holes. ( 3 ) on the front half of pressure surface, the effectiveness increases with decreasing blowing ratio at the downstream near the cooling row and it is contrary at the downstream far from the cooling row. ( 4 ) on the rear pare of the pressure surface, the effectiveness decreases with increasing blowing ratio and does not vary so much downstream in the cases of higher blowing ratio
研究結果表明葉片吸力面端壁附近區域壓力系數分佈呈現出較強的三維特性，動葉吸力面尤其明顯；氣膜孔流量系數隨吹風比的增加而增大，在高吹風比情況下，流量系數逐漸趨于常數；在不同型面區域，冷卻效率分佈有較大的差異，而且吹風比與主流雷諾數的影響程度也不盡相同；低吹風比下，孔出口下游附近可以得到較好的冷卻，中、高吹風比下，冷氣射流在加速流動主流的作用下返回壁面進行二次冷卻，孔下游較遠區域可以得到較好的冷氣覆蓋。 -
After the optimizing system is put into operation, online calculating results and operation effect is analyzed, pointing out that the base for the whole boiler soot blow optimization is the minimum loss of soot accumulation and energy consumption of soot blowing, the base for water cooling wall soot blow optimization is the combustion house outlet gas temperature difference, the base for a single heat exchange surface soot blow optimization is the degree of its soot accumulation
並對優化系統在線運行后，取得的實時計算結果和實際效果進行了分析，著重指出積灰和吹灰的經濟性最佳可作為整個鍋爐吹灰優化的決策依據，爐膛出口煙溫差可以作為爐膛吹灰優化決策的依據，受熱麵灰污程度可以作為單個對流受熱面吹灰優化決策的依據。 -
The igneous rock is the rock that the underground hot melting magma invading stratum or blowing off the earth ' s surface and then through condensing, piling up and solid
火成巖是地下高溫的熔融巖漿侵入地層或噴出地表經冷凝、堆積、固結而成的巖石。 -
Above all, the surface of the gas turbine blade including stator and rotor heat transfer coeficience with no film cooling hole was studied with the main stream reynolds number of 150000, 200000 50000, 300000, 350000, 400000. then, the heat transfer coefficience when all cooling holes opened and only one cooling hole opened was studied partly. and it ' s studied how the mainstream reynolds number, blowing ratio and the position of holes affect the heat transfer coefficience of the surface of blade
對導葉和動葉，都是先研究了在150000 ， 200000 ， 250000 ， 300000 ， 350000 ， 400000雷諾數下，沒有氣膜冷卻時的表面換熱系數分佈，然後研究了氣膜孔全打開和只打開單排孔時的表面換熱系數分佈曲線，重點研究來流雷諾數，吹風比和不同孔位出流對換熱系數分佈的影響規律。 -
