Laser Diagnostics of the Spray Cone Structure in Liquid Dispersion by Sprayers

A procedure and a setup for determining the spatial distribution of the concentration of droplets in a spray cone formed as a result of liquid dispersion by sprayers are described. The proposed procedure is based on measurement of the spectral coefficient of spray cone transmission during laser scanning over the chords of the different sections of the spray cone with subsequent solution of the corresponding inverse problem (of Abel′s equation). The characteristics of the structure of the spray cones obtained with the use of ejective and centrifugal sprayers are given.
