- Abstract
- The temperature and soot particle measurement technique in a laminar diffusion flame
has been studied to investigate the characteristics of soot particle with temperature
using a co-flow burner. The temperature distribution in the flame were measured by
rapid insertion of a R-type thermocouple and the soot particles by LEM/LIS techniques.
In these measurement, soot volume fraction, number density and soot diameters were
analyzed experimentally. As a results, the spacial distributions of particle volume
fraction, soot diameter, and number density are mapped throughout the flame using
the Rayleigh theory for the scattering of light by particles. A laser extinction
method was used to measure the soot volume fraction and laser induced scattering
method was used to measure the soot particle diameter and number density. Also, we
measured temperature without the effect of soot particles attached to the thermocouple
junction, which is close to the nozzle. In this result, we found that upstream zone has
a unstable flowing in co-flow diffusion flame and the y-axis temperature of flame has
a uniform temperature distribution in the most soot volume fraction zone.
