Abstract

We describe a laser induced incandescence (LII) measurement system for 2D mapping of non-volatile particulate matter (soot) in full-scale aero-engine exhausts. Simulation allows us to quantify the sensitivity of the measurement to variation in physical properties such as primary particle size, over a range of laser fluences and as a function of beam diameter. We discuss the implications of our results for optimisation and calibration of soot imaging in exhaust streams.
