One of our primary research goals at the UNSW Engine Research Laboratory is enhanced understanding of soot particle structures within the flame in high-pressure transient combustion environments – i.e. diesel engines. To clarify the sooting flame development, various opti-cal/laser-based imaging diagnostics are performed in an optically accessible diesel engine, which include high-speed imaging of hot soot luminosity, intensified imaging of cool flame and hydroxyl radical (OH*) chemiluminescence, planar laser-induced fluorescence (PLIF) imaging of fuel and OH and incandescence imaging of soot (soot-PLII). In the same engine, soot parti-cles are sampled directly from the diesel flame by means of thermophoresis and analysed using transmission electron microscopy (TEM) to clarify their size distribution and morphology. This seminar introduces these experimental approaches and some of the major findings made based on the image analysis.
