“…heights above the burner, while in reality the temperature decreases as soon as soot is formed and radiates (Tsurikov et al, 2005). The deviation of the assumed gas temperature never exceeds 100 K up to a height of 14 mm above the burner (Malarski et al, 2005).…”

Particle size distribution functions (PSDF) and mean particle sizes have been determined in a laminar premixed ethylene/air flame with three different experimental approaches: photo-ionization mass spectrometry (PIMS), scanning mobility particle sizing (SMPS), and laser-induced incandescence (LII). The main goal of this investigation was the crossvalidation of these three methods used at our institute for the determination of particle sizes in a great variety of flames or exhaust gases. We found good agreement between the three methods in the ranges where they are comparable as well as a complementary behavior for the different size ranges. PIMS and SMPS are able to measure the particle size distribution functions with good resolution. PIMS is favorable in detecting the smallest particles (<6 nm) and thereby able to detect even bimodal distributions of the soot precursor particles. SMPS and LII are suitable in the mid-and upper range of the particle sizes (>2 nm and >3 nm, respectively). LII offers the particular advantage of being a non-intrusive method. This makes it applicable in extreme environments, such as high pressure flames, as well as in very sensitive flames because no probe is needed.

“…The fluorescence was detected in a separate experiment after the LII measurement with the same camera equipped with a filter at 700 nm to minimize the influence of stray light. In contrast to other published data, where the integral extinction over the whole flame is measured [57], our set-up using the full sheet resolution allows to choose a suitable calibration height after the measurement [58].…”

a b s t r a c tLaser-induced incandescence (LII) has emerged as a promising non-invasive technique for measuring spatially and temporally resolved soot volume fraction and size. In this investigation we try to assess its performance in more detail by characterizing primary particle sizes using time-resolved LII and soot volume fractions by 2D LII. The experiments were performed at a fixed location in premixed ethylene/air flames burning on a sintered stainless-steel plug (McKenna) burner with varying values of the equivalence ratio for primary particle sizing and on the burner axis for concentration measurements. Maximum soot concentrations follow a power law behavior with equivalence ratio. The primary particle sizes obtained from LII decay curves are in good agreement with the values measured by other techniques and show a clear rise of particle size with equivalence ratio. The data analyzed with the help of a validated LII model will be useful for the further development of soot formation models.

“…Among the directly relevant flame work at high pressure are the study of co-flow diffusion flames to measure ''mature'' soot particles [20][21][22] and two contributions with a focus on PAH and soot precursor concentration [19,23]. For completeness, we also list the work in premixed flames at high pressure on ethylene up to 7 MPa [24], and in the range 0.1-0.5 MPa with ethylene, propene and toluene [25]. In all these studies, with the exception of [19], the presence of PAH and nuclei in the transition from gas to solid is obscured by the high soot load exhibited by the flames.…”
