  1. It is showed that numerical calculation could give the same position of separation line with the cold gas simulation. however, numerical simulation result is of a little deferent from cold gas simulation in some details, such as recirculation velocity and turbulent intensity. the main problem of numerical simulation is that the turbulent model is not perfect, and the computational grid is not precise enough

    利用實驗結果對數值模擬的準確性作了檢驗和評價，結果表明數值模擬能給出與實驗結果一致的分離線位置，但在某些流動細節上還有差別，如迴流速度大小和湍流度等，數值模擬中存在的主要問題是湍流模型不夠完善和網格生成不夠精細。
  2. Exhaust - gas - recirculation

    排氣再循環閥
  3. Thereby this paper puts forward four ways to reduce no, emissions : reduction of the highest combustion temperature, fuel emulsification, exhaust gas recirculation and selective catalytic reduction. according to the marpol convention, no, emissions are defined as per engine power of nox mass flow rate

    Marpol公約附則規定的no _ x的排放標準為柴油機單位制動功率排氣中no _ x的質量流量（單位： g kw ? h ） ，因此要想對被測試的柴油機的no _ x排放進行判定，必須得到排氣中no _ x的質量流量和柴油機的制動功率。
  4. The results indicate that the recirculations are caused at the closed end of the main duct and near the lower wall of the main duct in the lower side duct, and the secondary recirculation in the main duct ' s cross section, which appears only near the lower side duct, is caused due to section enlargement as gas enters the main duct from the side duct, when gas enters only at the entrance of the side duct

    實驗結果表明，在只有支管進氣的情況下，在總管的封閉端和支管下游總管壁面處產生了迴流；以及氣流從支管進入總管後由于截面擴張在總管橫截面上所誘發的二次流，並且二次流現象只發生在支管下游附近的總管橫截面上。
  5. 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

    兩個進氣道在補燃室周向成180度布置，有利於增強燃氣同空氣的摻混； 4在進氣道出口增加空氣分流擋板，有利於增加進入頭部的空氣流量，提高燃燒效率； 5增加燃氣噴管數量能增強燃氣同空氣在頭部的燃燒效果，為燃燒的進行創造良好的條件； 6
  6. The simulations results show that the average combustion temperature is much lower in fuel - rich state and little higher in oxygen - rich state near the best o / f ratio. by extending the post - chamber length the oxidizing gas and the fuel pyrolytic gas can burn completely and the average combustion temperature can be prominently increased. the fuel - rich recirculation zone close to the head of combustion chamber is very important for the combustion

    計算結果分析表明：發動機在富燃狀態下平均燃燒溫度偏低，在接近理想配比的富氧狀態下平均燃燒溫度有所提高；加長補燃室可以大幅度提高發動機的平均燃燒溫度，並促進氧化劑氣體和熱解氣體的充分燃燒；燃燒室頭部的富燃迴流區對發動機的燃燒非常重要，去掉燃燒室頭部突擴段后，氧化劑氣體和燃料熱解氣體不能充分燃燒，發動機的平均燃燒溫度大幅下降。
  7. Egr - so exhaust gas recirculation shutoff

    排氣再循環關閉
  8. Egrc exhaust gas recirculation control

    排氣再循環控制
  9. Egrv exhaust gas recirculation vent

    排氣再循環排除
  10. Egr exhaust gas recirculation

    排氣再循環裝置
  11. Exhaust gas recirculation

    排氣再循環
  12. At the preliminary stage of burning the gas flows along the back surface of the submerged nozzle and no recirculation forms in the aft - end cavity. at the medium stage of burning a weak recirculation forms in the rear of aft - end cavity by the force of injection flow. at the end stage of burning the flow separates at the c ombustion channel and a strong vortex forms in the aft - end cavity

    實驗結果表明，在發動機工作過程中隨著燃面的退移，燃燒室尾部的流動會發生很大變化，初始時刻背壁區加質流沿噴管背壁進入噴管，背壁區沒有迴流形成；中間時刻在加質流的驅動下背壁區後部形成較弱的迴流；結束時刻氣流在燃燒室壁面分離，背壁區形成強烈的迴流。
  13. Egrv exhaust gas recirculation valve

    廢氣再循環閥
  14. Nowadays, swirling burners have been used widely, because they can establish central recirculation bubbles which make high temperature gas flow back so as to speed up the progress of combustion of pulverized coal

    旋流燃燒器因為能夠形成中心迴流區，卷吸高溫煙氣，促進煤粉的著火等特點，在工程上已經得到了廣泛的應用。
  15. Study of the cooled exhaust gas recirculation system using in the diesel engine

    冷卻式廢氣再循環系統在柴油機中運用的研究
