Investigation of soot processes in turbulent nonpremixed hydrocarbon flames based on laser scattering and extinction experiments

The principal objective of this study was to investigate the fundamentals of various soot processes within turbulent non-premixed flames using non-intrusive laser diagnostics. Unconfined burners with different fuels in atmospheric-pressure air were selected to collect data in well-defined turbulent flames. Laser scattering at two angles and extinction experiments were conducted and interpreted based on an optical theory which can properly account for the actual fractal morphology of soot aggregates...with the ultimate objective of advancing the predictions of fine-particulate matter in practical combustion applications --Introduction, pages 16-17
