Co-flow laminar diffusion flames' temperature has been studied experimentally for ethylene( C2 H4) using a co-flow burner in order to investigate the characteristics of diffusion flame's temperature distribution. The temperature distributions in the flame were measured by rapid insertion of a R-type thermocouple. The measurement area was{{br}}divided into three zones. Ist area was expect to created PAH zone, II nd area was expect to form soot zone, which is known to generate most soot volume fraction, and III rd area was expect to form soot oxidization zone. Also The temperature along the flame y-axis as a fuel quantity was measured. As a results, we have measured temperature neglecting the effect of soot particles attached to the thermocouple junction, which is close to the nozzle and upstream zone has a unstable flow in co-flow diffusion flame and acquires that the flame y-axis temperature has a uniform temperature in the generated soot volume fraction zone(II nd).{{br}} |
