During the past year, significant progress was made in three different areas: measurement of droplet velocity distributions, applications of the polarization ratio sizing technique, and studies of fuel property effects on spray flame structure. Droplet velocity distributions were obtained with a single-component laser velocimetry system to obtain detailed information on the transport of individual droplets. The polarization ratio technique is being developed to obtain instantaneous droplet sizes in nonburning and burning sprays. Droplet size and velocity measurements were obtained with phase/Doppler interferometry for four different fuels to ascertain the influence of physical properties of fuels on the size, number density and velocity of droplets found in spray flames.
