Abstract
Fuel droplet evaporation plays an important role in liquid fuel combustion systems. Laser-induced iodine fluorescence can be used to make nonintrusive concentration measurements in a plane with good spatial and temporal resolution. Iodine seeded droplets were suspended on a hypodermic needle, and fluorescence was induced in the resulting vapor cloud. Photographs or video images of iodine seeded 1-octanol droplets provided direct measurement of concentration. Quantitative analysis of free falling droplets was obtained by using a photomultiplier tube to image a single point near the droplet. Reconstructions from multiple photomultiplier recordings indicate that the region of maximum concentration is displaced from the droplet axis and moves behind the drop with increasing Reynold's number.
