Abstract—This study investigates the effects of injection
pressure and ambient temperature on distribution of number
density and diameter of fuel droplet in diesel fuel spray by
using shadow-graph photography technique. The large number
of fuel droplets was statistically analyzed by newly developed
algorithm. The results show that the larger-size particles exist
closer to the spray tip. Higher injection pressure promotes
atomization and high ambient temperature has great effect on
formation of small-size droplet at early time of injection period,
especially at up and midstream of the spray.
Index Terms—Atomization, spray images, shadowgraph,
droplets measurement.
