Abstract
In this paper a comprehensive review of flow visualization techniques used for the analysis of spray characteristics is
presented and an experimental demonstration of different lighting techniques has been made. Still photographs of
sprays from an airblast atomizer and a swirl atomizer are taken under backlighting, slit lighting, incident lighting
(front flash) and a new method of capturing scattered light image at 1200 to the incident light is introduced in the
present work. Photographs taken by these methods are shown to be useful for deriving useful observations such as jet
breakup phenomenon, the internal details and the external appearance of the spray. It is demonstrated that the
information obtainable from each technique is different and that a combination of different techniques may be
necessary for proper diagnosis. The article also includes a discussion on the jet breakup phenomenon as observed in
the photographs and in addition a new concept of shear formation of smaller droplets from the surface of a liquid jet
by the co-flowing air stream in an airblast atomizer has been proposed.
