CARS를 이용한 희박 예혼합 가스터빈 연소기내 온도 측정 (Ⅰ)-연료/공기 혼합정도가 위상별 온도에 미치는 영향-

다국어 초록 (Multilingual Abstract)

Experimental investigations were earned out in an atmospheric pressure, optically accessible and laboratory-scale dump combustor operating on methane gas The objective of this study was to obtain the phase-resolved gas temperatures at different phases of the oscillating pressure cycle during unstable combustion CARS temperature measurements were made at several spatial locations under lean premixed conditions to get the information on temperature field within the combustor Also the effect of incomplete fuel-air mixing on phase-resolved temperature fluctuation was investigated Results including phase-resolved averaged temperature, normalized standard deviation and temperature probability distribution functions (PDFs) were provided in this paper Temperature PDFs gave an insight on the flame behavior And strong correlation between phase-resolved temperature profile and pressure cycle was observed Results of the phase-resolved high temperature gave an additional information on the perturbation of equivalence ratio at flame as well as the effect of mixing quality on NOx emission characteristics.
