Numerical Studies on Soot Formation Characteristics of Turbulent Non-premixed and Partially Premixed Flames

난류 비예혼합 및 부분예혼합 화염장에서 매연입자의 생성특성 해석

The present study is aiming at numerically analyze the soot formation processes coupled with gas reaction mechanism in turbulent non-premixed and partially premixed flames. In order to realistically represent turbulence-chemistry interactions with detailed chemical kinetics and soot formation behaviour related to the turbulent non-premixed and partially premixed flames, the transient flamelet[1] and flamelet based level-set approach[2] are coupled with soot formation based on the two equation model [3] and DQMOM (Direct Quadrature Method of Moment)[4].
