液體燃油.煤油和噴氣發動機燃油發煙點的測定Source : major automobile exhaust ( mainly in the combustion of gasoline is not sufficient, if the state open parking engines, coal burning reclamation, combustion of organic compounds )
主要來源：汽車尾氣（主要在汽油燃燒不充分時，如停車狀態開發動機、燃煤、農墾燒荒、有機物燃燒） 。The convective term is solved by ausm + ( a sequel to ausm which means " the advection upstream splitting method " ). the 7 species 8 steps model and 7 species 7 steps model of hydrogen / air is used in the hydrogen reacting flowfield, the 9 species 5 steps model of methane, the 10 species 10 steps model of ethane and the 10 species 13 steps model of kerosene are used in the hydrocarbon reacting flowfield, the results of the distributions of velocity, mach number, pressure, static temperature, total temperature, species mass fraction and the combustion efficiency are gained, and the numerical results of the pressure of hydrogen and methane are compared with those of the experiment
計算中通量項採用ausm +通量分裂格式，氫反應流場採用氫/空氣的七組元八方程模型和七組元七方程模型，碳氫反應流場採用甲烷的九組元五方程模型、乙烯的十組元十方程模型和煤油的十組元十三方程模型，得出了超燃發動機燃燒室流場的速度、馬赫數、壓力、靜溫、總溫和組元質量分數分佈及燃燒效率等性能參數，其中氫和甲烷的計算壓力分佈與實驗結果進行了比較。The mainly works had been done as follows : 1. in order to keep commonality, the modules who have similar thermodynamic process had been classed. such as evaporating module ( including furnace, drum, system of boiler recycled water ), single - phase heat exchange module ( including superheater, reheater, ecomomizer ), lubricating oil system module ( can be used for any lubricating oil system of rotation mechanical impedance ), pump and fan module, ect
本文所作的主要工作如下: 1 、為保證模塊的通用性，對鍋爐有相似熱力環節的模塊進行分類，建立模塊庫，便於模塊調用，如蒸發區模塊（包括爐膛、汽包和爐水循環系統） ，單相換熱模塊（包括過熱器，再熱器，省煤器等） ，潤滑油系統模塊（可用於各種轉機軸承潤滑油的動態特性的計算） ，泵與風機的動態計算模塊等。Then using kerosene as fuel, oxygen and compressed air as oxidizers, proof - of - principle experiments of pdre were successfully conducted the results show that the measured detonation wave pressures are close to theoretical values it also indicate that using kerosene as the fuel of pdre is feasible
採用航空煤油為燃料，氧氣和壓縮空氣為氧化劑，分別進行了兩相脈沖爆震火箭發動機原理性試驗，所測得的爆震波壓力接近充分發展的理想爆震波壓力，說明採用煤油作為脈沖爆震火箭發動機的燃料是可行的。For example, fuel - efficient motor vehicles must be developed to reduce oil co umption and alternative energy sources must be found to replace coal
例如，必須開發節能的機動車減少汽油的消耗量，並且必須找到可替代能源取代煤。It is absolutely essential to reverse the irrational misuse of nonrenewable resources. for example, fuel - efficient motor vehicles must be developed to reduce oil consumption and alternative energy sources must be found to replace coal
徹底改變對不可再生資源的非理性濫用是絕對有必要的。例如，必須開發節能的機動車減少汽油的消耗量，並且必須找到可替代能源取代煤。Under this background, we successfully developed an engine fuelled with coal - bed gas and ignited by spark plug. the measurements for the prototype engine were thoroughly made, including the cylinder pressure, the rate of heat release, combustion duration, ignition delays, spark ignition angle, and the fluctuation of the cylinder maximum pressure
在此背景下，本文對經由s195柴油機改裝得到的燃用變組分煤層氣發動機進行了全面的測試和分析，包括缸內示功圖、燃燒放熱率、主燃期、點火提前角、火焰發展期以及最大壓力循環波動等。Detonation pressure properties of kerosene aero - valve pulse detonation engine
