Abstract
Abstract In this work, time-resolved laser-induced
incandescence (TiRe LII) has been employed to measure
primary particle diameters of soot in an atmospheric laminar
ethylene diffusion flame. The generated data set
complements existing data determined in one single location
and takes advantage of the good spatial resolution of
the ICCD detection. Time resolution is achieved by shifting
the camera gate along the LII decay. One key input
parameter for the analysis of time-resolved LII is the local
flame temperature. This was determined on a grid
throughout the flame by coherent anti-Stokes Raman
scattering. The accurate temperature data, in combination
with other published data from this flame, are well suited
for soot model validation purposes while we showed feasibility
of a shifted gate approach to deduce 2D particle
sizes in the chosen standard flame.
