LES/PDF modeling of autoignition in a lifted turbulent flame: Analysis of flame sensitivity to differential diffusion and scalar mixing time-scale

, 2016
The stabilization of lifted flames involves a complex competition between small-scale mixing and propagation of flame kernels at the base of the flame. Here, the effect of species diffusivity on this stabilization process is explored. For this purpose, a

拡散火炎のPLIF計測と熱発生速度の検討 [PDF]

, 2010
Although heat release rate is one of the important combustion characteristics, its direct measurement is impossible. Recently, Najm et al. have reported that the heat release rate is well correlated with the product of OH and HCHO fluorescence signals in
