Liquid length is now defined based upon projected liquid volume. Liquid length data for Spray A using a projected liquid volume definition is available for nozzle 370 at this site.

DescriptionTime-resolved liquid length determined from high-speed Mie-scatter imaging using a 3% threshold of maximum intensity as recommended by Siebers. Mean liquid length for the steady period between 0.5 to 5.0 ms is 10.4 mm using this criteria. Dataset provides time-resolved mean, standard deviation, and uncertainty for an ensemble-average of 18 injections. See Pickett, 2011 for a summary of the problems associated with Mie-scatter lighting.PNG image is the time-average for the steady period between 1.0 to 5.0 ms. Axial and radial profiles may be extracted from this image using "save link as" and image scaling information. Interpret with caution because of non-uniform lighting and light extinction. Image setup for high-speed movies found here for Mie scatter 181. Light enters from the bottom.Line-of-sight optical thickness (τ) extinction data are averaged during the steady period between 1.0 to 4.0 ms. Axial and radial profiles are available using the .csv files above. Image setup for high-speed diffused back illumination 303 is here. Please be aware that beam-steering effects in the vapor phase may contribute to erroneous liquid extinction as discussed in Manin, 2012. For example, vapor-phase beam steering (interpreted as extinction) persists downstream of the liquid length at 15 mm.Text file of axial distance and centerline optical thickness (τ). Time-averaged optical thickness (τ) during the steady period of injection from a 0.5 mm HeNe laser (633 nm) passing through the centerline of the spray (Pickett, 2011). Collection is made with 220 mrad angle to account for vapor-phase beam steering, which persists in the DBI setup as discussed in Manin, 2012.
