本文從氫燃料的物化特性和燃燒特徵著手,通過分析氫空氣混合氣燃燒的湍流火焰結構和燃燒化學反應動力學,基於雙區燃燒模型,建立了包括雙區熱力學、準維湍流卷吸燃燒、湍流火焰傳播速度、氫空氣混合氣燃燒化學反應動力學以及傳熱損失等模塊的燃燒模型,並給出了相應的計算方法。It is found that the liquid kerosene of injection upstream cavity could finish the process of atomization and evaporation in short distance, and enter into cavity through convection. aft wall is the primarily area of flame holding in cavity, and the only area when near the lean blowout limit, flame in area of fore wall are spread from it. cavity shear layer in reaction flow angle greatly to the main flow direction, and couldn ’ t reattach to aft wall anymore, it appears great difference in characteristics of cavity flowfield between non - reaction and reaction state
研究發現:凹腔上游噴注的液體燃料能夠迅速霧化、蒸發,並在較短距離內依靠對流輸運過程進入凹腔內部;凹腔後壁始終是凹腔火焰駐留的主要區域,在貧油極限時,也是唯一區域,並存在明顯的火焰由後壁向前壁的傳播過程;燃燒狀態下的凹腔剪切層以較大角度向下游主流發展,不再附著于凹腔後壁,與冷流中的凹腔流場特徵相差較大。Influence of catalytic reforming reaction for premixed gases with h2 on flame propagation velocity
