本文針對某種航空發動機火焰管模型結構,採用數值模擬方法對「摻混空氣噴射角度對燃燒室性能的影響」這一問題進行了探討。Products function : put our “ sun shine ” brand carbon steel fiber evenly seep into concrete to form steel fiber reinforced concrete and it can decrease the thickness of reinforced concrete by half, it not only shorten the project time, save the material and manpower expense, bring distinct economic benefit, but also increase the performance of crack resistance, percussion resistance, tensile strength, bend resistance. scosspr resostamce amd wear resistance of the reinforced base materials. if the weight ratio of 2 % steel fiber seep into the concrete, it can solve the brittleness problem of the concrete, in the condition of 60 % ralative air humidity, after 21days air - dry, even 520 days air - dry, it ' s difficult to find any crack by eyesight, the bend resistance for the steel fiber concrete is 140 times stronger than the concrete without steel fiber, the capability of impact resistance increase 10 times
產品功能:將本公司「雙興」牌碳鋼纖維系列產品均勻地摻入混凝土中,形成鋼纖維增強混凝土,可使工程中鋼筋混凝土的施工厚度降低一半,不僅縮短了施工工期,節省了材料和人工費用,帶來顯著的經濟效益,且增強了基體的抗裂、抗沖擊、抗彎、抗剪、耐磨擦等性能,如摻入本公司2 %鋼纖維的混凝土,不僅解決了混凝土的脆性問題,在空氣相對濕度60 %的條件下風干21天後,甚至在風干520天,肉眼很難發現裂縫,摻入鋼纖維后的增強混凝土比不摻鋼纖維的混凝土抗彎強度提高140倍,耐沖擊荷載提高10倍。What inconvenienced him most was the stuffy, dense, overheated air of the place with its strong, haunting smell, a smell peculiar to this part of a theater, and, as such, compact of the reek of gas, of the glue used in the manufacture of the scenery, of dirty dark nooks and corners and of questionably clean chorus girls
這空氣既混濁又悶熱,裏面還摻雜著一股濃烈的氣味。這是后臺傳出來的氣味,有煤氣的氣味,有布景上的膠水的氣味,有陰暗角落裡的臟味,還有女群眾演員的不幹凈的內衣的氣味。The effect of storage time, syringing of methane and different gas adulteration on the activity of methane was studied
摘要討論了甲烷貯存時間和各種洗氣劑對甲烷活性的影響,研究了不同摻雜氣體對甲烷與空氣混合的爆炸極限影響。While the speed is very large, the fuel - air mixing behind the airstream is decreased and the span that the fuel flow in the second combustor is reduced, so the combustion efficiency is decreased, h ) if the fuel streams impinge with the airstreams directly at the air - inlet exit, it make against increasing the combustion efficiency, i ) increasing air - to - fuel ratio within proper range can increase the combustion efficiency
增加燃氣噴射速度有利於增強迴流區強度,頭部燃燒溫度上升,但速度太大則會減弱燃氣同空氣在進氣道下游的摻混燃燒,減少燃氣在室內停留時間,燃燒效率降低; 8燃氣射流與空氣流在進氣道出口直接撞擊不利於燃燒效率的提高; 9在適當范圍內增大空燃比能顯著提高燃燒效率。The mixing of air and fuel can be improved, d ) adding air distributary valve at exit of air - intake can increase the amount of air bifurcated into the dome region, so the value of combustion efficiency is increased, e ) increasing gas generator nozzle number can improve combustion characteristics in the dome region and produce good condition for combustion progress, f ) when the fuel streams are ejected into the second combustor with a angle, the combustion efficiency is increased, g ) when the speed of fuel streams increased, the intension and temperature of recirculation region is improved
