An experimental study has been made of the instantaneous two-dimensional visualization of soot distribution profile in continuous spray flames. The spray flame was formed by a pressurized-type spray injector. LCO was selected as the test fuel, and the effect of additives, water (emulsion) and alcohol, on soot formation in the spray flame was examined. Cross sections of the spray flame were illuminated by a sheet of incident laser light. The successive images of the scattered light were recorded by using a CCD camera with a gated image intensifier. The results showed that the high concentration region of soot existed in the spray flames, and that the soot concentration decreased downstream. 20% addition of alcohol was found largely reduced the soot formation.
