本研究開發了一套用於量測微槽內爆震波溫度分布之影像測溫法。藉由彩色高速攝影機獲得爆震波可見光範圍之原始影像經過校正與解算得到爆震波之溫度分布。並針對在不同當量比、管槽尺寸、燃料種類條件下之爆震波溫度分布進行比較，且擷取一維之整體平均溫度、中心軸溫度、邊界溫度及縱截面溫度分布進一步探討熱損之影響。研究結果說明爆震波在接近化學當量時有最高溫度且當量比越增加則溫度越低，與ZND及CEA理論之趨勢相同，但是在貧油端因燃料佔比較少，使得爆震波脫離灰體假設，導致溫度有高估之情形。在管槽尺寸影響方面，發現較窄之管槽尺寸下，因表面體積比增加而導致熱損增加使得爆震波溫度較低，後續隨著管槽尺寸增加而熱損越少，故溫度值越接近無考慮熱損之理論溫度值。而在三種不同碳氫比之乙炔、乙烯及丙烷燃料中，碳氫比最高之乙炔最接近灰體假設，因此獲得之溫度與CEA及ZND最為接近，同時在一維平均溫度分布中顯示乙炔高於乙烯及丙烷700 K左右，與ZND所預測之結果相似。同時藉由爆震波之縱截面溫度分布顯示了在任何條件下之爆震波都具有與ZND概念相同之誘導區及反應區，詮釋了未燃氣在誘導區受到震波壓縮加熱至約2000 K，後續進入反應區使得溫度進一步上升。且發現在0.25 cm截面處溫度邊界層開始產生，且隨著距離增加邊界層厚度亦增加，熱損之影響越嚴重。

This research has developed a set of image imaging thermometry for measuring the temperature distribution of detonation waves in the microscale channel. The original image of the detonation is obtained by a color high-speed camera is calibrated and calculated to obtain the temperature distribution of the detonation wave. And compare the detonation wave temperature distributions under different equivalence ratios, channel size, and fuel types. The results show that the detonation wave has the highest temperature when it is close to the stoichiometric, and the higher the equivalence increases, the lower the temperature, which is the same trend as the ZND and CEA theory. But at the fuel lean, the proportion of fuel is less, which makes the detonation wave deviate from the gray body hypothesis, resulting in an overestimation of the temperature. In terms of the influence of the tube channel size, under a narrower channel size, the increase in heat loss due to the increase in the surface volume ratio makes the detonation wave temperature lower. Among the three fuels of with different carbon-hydrogen ratios, the acetylene with the highest carbon-hydrogen ratio is closest to the gray body hypothesis, and it is not affected by the boundary heat loss, so the temperature is very close to the theoretical value. Propane is the fuel is more severely affected by heat loss, making the temperature deviation larger than the other two, but the overall trend is similar to the theoretical value.
