  A Visual investigation of spray cone angle for different air-blast atomizers
and flow conditions is described. Liquid jets are exposed to high gas stream
with specific relative angle. Using high speed camera, spray cone angle over a
range of Reynolds number 4x104 to 9x104 and Weber number 1 to 140 is studied,
followed by laser-based diagnosis of particle distribution and Sauter mean
diameter. The results show that for high Reynolds and Weber number, the cone
angle is independent of flow condition, and is only dependent on geometry of
atomizer, including orifice diameter with significant effect on cone angle,
Sauter mean diameter and particle distribution
