本研究主要分為兩部份探討微小尺度爆震管之實驗，第一部份為添加臭氧對於丙烷/氧氣1×1 mm2的方形微槽利用火焰螢光和schlieren顯影，觀察緩燃焰轉爆震波之影響、火焰加速、爆震波傳遞之變化。可以發現在貧油及化學當量之情況下，在緩燃焰中添加臭氧之反應波速度會較未添加來的快且更快轉為爆震波。而在越貧油之條件下，添加臭氧所影響之爆震波轉變時間越多，而在轉為爆震波後，發現在爆震波階段中有無添加臭氧不管在貧油或富油之階段對於爆震波速度並沒有太大之影響。
第二部份為探討乙烯/氧氣從點火到緩燃焰轉變為爆震波之過程，首先針對化學當量的乙烯/氧氣在1×1 mm2的方形微槽利用高速schlieren顯影探討反應波與震波動態解析，並且著重探討震波叢集階段，進一步改變乙烯/氧氣之當量比，觀察震波叢集階段之流場特徵，發現在當量比為1.3時-angle為最小，且趨勢為U型曲線且與爆震波轉變之時點趨勢為一致。乙烯/氧氣在改變管槽尺寸條件後，發現在管徑縮小時，流場特徵的時點都提早，但-angle卻是隨著管徑變小而變。最後觀察燃料種類及臭氧之添加對於震波叢集特徵之影響。

To investigate the flame acceleration process in narrow channels on the high-speed visualization systems were used. The study is divided into two parts to explore the experiment of microscale detonation channel. The first part is that the addition of ozone to the propane/oxygen in 1×1 mm2 channel size using chemiluminescence and schlieren to observe the flame acceleration, deflagration-to-detonation, and steady detonation propagation. It can be found that in the condition of fuel lean and stoichiometric, the adding ozone is faster than no-adding ozone to generate DDT. Adding ozone in the case of fuel rich does not have much effect on generating DDT. After the detonation is generated, the addition of ozone has little effect on the detonation propagation. The second part is to explore the process of ethylene/oxygen flame acceleration and deflagration-to-detonation transition and focus on the stage of shock cluster. We use the high-speed schlieren to analysis the relationship of the reaction wave and shock wave. Experiments show that a coupled shock cluster – reaction front structure emerges prior to detonation transition in ethylene/oxygen mixture in small channels. The structure features checkered oblique shock pattern interweaved with reaction front. It is found that the angle between the parallel oblique shocks in the structure and the side wall, defined as -angle, does not change over time in a certain mixture. And observing the characteristics of shock cluster as a function of equivalence ratio and channel size.
