A collection of three reports presents an expanded discussion of the topic of "Optical Diagnostics of High-Pressure Liquid Fuel Sprays" (LEW-16701),NASA Tech Briefs, Vol. 23, No. 3 (March 1999), page 18a. The reports describe experiments in which fuel sprays representative of those in liquid-fueled, high-pressure gas turbine combustors were analyzed by a combination of planar laser-induced fluorescence imaging, planar Mie scattering, and phase Doppler particle analysis. The earliest of the reports ("Fuel Injector Patternation Evaluation in Advanced Liquid-Fueled, High-Pressure, Gas Turbine Combustors, Using Nonintrusive Optical Diagnostic Techniques") was the subject of the noted prior article.
