다국어 초록 (Multilingual Abstract)

It is shown that the effect of variable parameters on flame structures and NOx emissions in the laminar<br/>
partially premixed methane-air flames with a co-axial Bunsen burner. Objectives of this paper is to<br/>
understand the effects of flow variables on NOx emissions and the flame structure with OH<br/>
chemiluminescence, including reconstructed image by abel inversion processing at each conditions. A fuel<br/>
flowrate of 200 [cc/min] was fixed and the amount of air was varied from 400 to 1200 [cc/min]. The<br/>
experimental variables were equivalence ratio( ), fuel split percentage( ) and inner tube recess(x/D). Flow<br/>
conditions were ranged from 1.36~4.76(equivalence ratio), 50~100(fuel split percentage) and 0~20(inner<br/>
tube recess). NOx analyzer and ICCD camera with a OH filter were used as a main experimental<br/>
apparatus. In addition, Abel inversion, which is a kind of tomography and valuable to estimate a<br/>
two-dimensional structure of co-axial flames from cubical information, was employed for combustion<br/>
diagnostics. Results from this study indicate that the main effects depend on equivalence ratio and next<br/>
sigma, x/D for NOx production and OH formation. Throughout Abel inversion, we could affirm the<br/>
maximum position and the tendency of OH radical intensity by variants at five axial heights above the<br/>
burner exit.
