| 초록 |
Planar laser indecued fluorescence(PLIF) has been widely used to obtain 2D fuel distribution. Preliminary investigation was performed to measure quantitative air excess ratio distribution in an engine fueld with LPG. It is known that fluorescence signal from acetone as a fluorescent tracer is less sensitive to oxygen quenching than other dopants. Acetone was excited by KrF excimer laser(248mm) and its fluorescence image was acquired by ICCD camera with a cut-off filter to suppress Mie scattering from the laser light. For the purpose of quantifying PLIF signal, an image processing method including the correction of laser sheet beam profile was suggested. |
