吾人嘗試以新型燃燒方式，透過添加強氧化劑來輔助燃燒與控制火焰型態。強氧化劑分別為三種：不同氧氣濃度下之氮氣與氧氣混合氣(定義Ω)、氧化亞氮(N2O, Nitrous oxide)與過氧化氫(H2O2, Hydrogen peroxide)。本實驗以同軸三環燃燒器進行。藉由中心管通入氧化劑，第二環為燃料甲烷，最外環為空氣，檢視不同氧化劑/燃料的出口流速比(R=V1/V2)下的火焰現象觀測，並且搭配理論預測模型探討影響火焰外型變化之參數。理論模型顯示，噴流出口流速、濃度與溫度的選定是影響火焰結構變化之重要參數 In order to avoid the combustion instability during lean operation for lower fuel consumption, the strong oxidizer concept, such as employing oxy-enriched conditions, nitrous oxide (N2O) or hydrogen peroxide (H2O2) to enhance combustion and control the fl
