| Popis: | National audience; Physical and chemical properties of soot emitted from airplanes are still poorly known due to the difficult access at the core of these systems, as well as the stringent conditions into or at the exhaust of the engines. It is challenging to directly measure soot particles inside aeronautic combustors due to the high pressure and limited optical access. Under these harsh combustion conditions, we try to identify the mechanisms participating in the formation of soot particles. These mechanisms are still subject to numerous questions due to the lack of experimental evidence and high demand for processing power requested by theoretical models. The solution to this problem relies on the coordinated efforts of researchers for the implementation of experimental and theoretical tools. To overcome the experimental challenges, this work focuses on the development and implementation of laser induced incandescence (LII), a technique used for the detection of soot volume fraction, as well as laser induced fluorescence (LIF), a technique used for the characterization of soot precursors. |
