Hydrogen addition to acetylene–air laminar diffusion flames: Studies on soot formation under different flow arrangements

“…8a-8c). A similar trend has been reported in previous studies of hydrocarbon-air laminar diffusion flames [11][12][13]25]. In these flames, soot formation and oxidation proceed at the same time, with the soot formation being dominant up to the maximum soot volume fraction location, and soot oxidation dominating the process thereafter.…”

Hydrodynamic suppression of soot formation in laminar coflowing jet diffusion flames

“…The measurements of Refs. [27] and [28] yield Cr _ 0.5 for soot-free blue flames and Cf _ 1.0 for flames at the laminar smoke point for flames in still air [22]. These assignments provide the good correlations of the present results in coflowing air seen in Fig.…”

The effect of strain rate on polycyclic aromatic hydrocarbon (PAH) formation in acetylene diffusion flames

“…Sunderland et al [19,24] reported studies on soot formation and temperature profiles in a turbulent diffusion flame. Sun et al [17] measured the temperature and major species concentration profiles in a counterflow diffusion flame of acetylene using the spontaneous Raman scattering technique.…”
