  1. 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。
  2. The flame holding technology based on cavity in supersonic combustion was studied systematically and comprehensively. the interaction between gas / liquid injection and cavity flow were studied in non - reaction flows

    論文選取基於凹腔的超聲速燃燒火焰穩定技術為研究對象，對凹腔燃燒流動過程和凹腔火焰穩定器性能進行了全面深入研究。
