摘要：
Laser induced incandescence (LII) is used in this study to measure soot volume fractions in steady and pulsed laminar diffusion flame. The main objective of this study is to investigate the effect of flame pulsing on soot formation inside the flame region. Phase-locked soot images were obtained for flame pulsing frequency between 10 and 200 Hz. The phase-locked soot images revealed the entire motion process of the soot field during one pulsation period. The results showed that the total soot volume fraction in the flame region increased by 45% when the pulsing frequency was increased from 10 to 200 Hz.
