摘要
A two-dimensional LII (2D-LII) experiment system was established to first measure the soot volume fraction distribution in the Gülder ethylene diffusion flame. Compared with the extinction method and the single-point LII calibration method, the experiment results show its validity. The 2D-LII setup was then used to investigate the effects of cottonseed oil on soot formation of vaporized diesel laminar diffusion flame produced on a liquid burner. The results show that with increasing the blending ratio both the maximum volume fraction and the total amount of soot decrease. In the flame centerline region, the soot volume fraction first increases with increasing the flame height to reach a peak and then decreases towards the flame tip. The peak value of the soot concentration appears in the flame-wing in the lower part of the flame and moves towards the flame centerline with increasing the flame height.
