  An experimental investigation of secondary atomization of spray in plain-jet
airblast atomizers with a circular array of six liquid jets is studied.
Crossflow of air with controlled velocity and pressure is applied to transverse
jets. The liquid jets (Re=12000) are injected into airflow (Weg of 1250-3000)
analyzed experimentally for different injection diameters of 0.8-1.6 mm.
Particle size distribution measurement is carried out by Malvern Mastersizer X
in the fully atomized region of the atomizer. The droplet size distribution in
the secondary or final atomization stage is also modeled by the Finite
stochastic Breakup model, which requires 4 parameters to be defined i.e.
initial droplet diameter, maximum stable droplet size, minimum mass ratio, and
droplet breakup probability. The modeling approximation is in very good
agreement with the experimental result. This remarkable consistency between
model and experiment is quite useful in terms of optimal atomization
performance by considering the dynamics of the liquid jet.
