burner inner liner-
And then, like a bursting roman candle, a gum tree ahead of us was shattered by a bolt of lightning
然後，如同一支爆發的羅馬焰火筒，我們前面的一棵橡膠樹被一道閃電摧毀。As a result, the life of the flame tube was calculated by using coffin - manson equation
結合coffin - manson規律對火焰筒壽命進行了預測，與實際情況的對比說明該假設是合理的。When flux appears liquid and transparent on both tube and valve, start sweeping flame back and forth along axis of joint to maintain heat on parts to be joined, especially toward base of valve socket
當焊劑變成液態並且在管道和閥門上呈現半透明狀態時，開始將火焰沿著連接部件的軸線進行進退烘烤，以保持連接部件、特別是閥門套筒底座部位的熱度。Jet impingement cooling is an advantage method in heat transfer enhancement owing to its extremely high local heat transfer coefficient and simple structure. as regard as the combustor flame tube cooling structure is concerned, the impingement - converse convection - film composite cooling is an effective method, in this composite cooling structure, the impingement cooling problem could be modeled as impingement inside semi - confined channel
對于沖擊-逆向對流-氣膜復合冷卻的火焰筒結構而言，火焰筒壁面冷氣側的沖擊冷卻實質上是半封閉通道的沖擊冷卻，即沖擊射流從沖擊孔板噴出，沖擊到換熱靶面后形成壁面射流沿通道單方向流出。Flame tube in aircraft engine undergoes high temperature and high speed airflow washing. a hypothesis was suggested, which takes the transient heat transferring as the main reason to the cracking and damage on flame tube. finite element method was adopted to simulate the thermal fatigue and the hypothesis was reproduced
發動機火焰筒的熱疲勞損傷是導致火焰筒失效的主要原因，本文提出了一種火焰筒熱疲勞損傷假設，認為火焰筒熱疲勞損傷不是由於發動機的運行和停車時冷熱溫度循環造成的，而是發動機啟動時瞬態溫度傳導過程中材料循環塑性變形的結果，利用該假設結合有限元計算模擬了火焰筒產生疲勞損傷的原因。The combustor do n ' t fail if transient rise of temperature field is neglected, the stress field of combustor can n ' t cause gas film wall rupture. 2. combustor ' s creep and relaxation is calculated in steady temperature field, the results show that creep and relaxation is not main reason destroying combustor chamber
對穩態溫度場下的蠕變鬆弛計算表明，高溫下的蠕變鬆弛促使火焰筒的熱應力下降，在所考慮的條件下穩態溫度場導致火焰筒的蠕變變形不是火焰筒破壞的主要原因。Through simulated results, we can receive ideal flamethrower shape, root air, and the obliquity of spin vane so that plateau oil - fired warm air heater ignition easily, flame is stabilization and burn sufficiency
從而得出使高原燃油暖風機易點火、火焰穩定、燃燒充分的噴火筒形狀、根部風的大小以及旋流葉片的傾斜角度，為工程技術人員設計高原燃油暖風機提供一定的根據。In order to study the influence of dimensional configuration of the film cooling hole on the discharge coefficient, some kinds of film cooling holes with different dimensional configuration were designed
摘要為了研究火焰筒壁面氣膜冷卻孔幾何結構對流量系數的影響規律，設計了幾種具有不同幾何尺寸和排列結構的氣膜冷卻孔實驗件。On the contrary, if temperature gradient is relatively low, combustor only undergo low compressive stress at high temperature. the combustor of engine has a longer life length. these results can provide some reference for maintain and design for gas turbine combustor
分析也表明，若在起動過程中筒壁的溫度梯度較為平緩，火焰筒的氣膜唇邊在起動完成後始終受微小的壓應力作用，火焰筒的壽命可以大大延長。In this thesis, in order to search the condition and reason of failure for a combustor, thermal stress was analyzed in steady and transient temperature field. according to the investigation, three conclusions are obtained
在忽略瞬態升溫過程得到的穩態溫度場作用下，火焰筒的熱應力不足以導致裂紋萌生，所以僅進行穩態分析不能得到合理的結論。If there are high temperature gradient between cool liner and hot liner, compressive plastic strain appear at that transient time, which lead to gas film wall bearing high tensile stress at high temperature. high tensile stress is one of main reasons which destroy combustor
分析表明，起動過程中由於熱傳導滯后引發的溫度梯度可以導致火焰筒氣膜唇邊在起動瞬間發生較大的壓縮塑性應變，進而使得該區域在工作時承受較高水平的拉伸應力，高的拉應力會導致火焰筒萌生裂紋。The combustor of gas turbine engine operates under inhomogeneous high temperature, which causes very complicated mechanical behavior of combustor ' s material, and makes combustor failure
燃氣渦輪發動機火焰筒在非均勻溫度場的作用下，材料會呈現復雜的力學行為，導致使用過程中出現裂紋而造成故障。分享友人
