Laser diffraction particle sizing techniques have frequently been employed to determine droplet size distributions in sprays. However, they are generally limited by problems due to obscuration of the laser beam by the spray, which can, at high levels, create ambiguity in data due to ''multiple scattering'' of the incident beam. Correction factors have been presented in the literature [1] to account for high levels of obscuration; however, convergence errors between the modified and recorded data create problems in the accurate representation of the spray. This study of the droplet size distribution produced during the atomization of detergent slurries by commercial centrifugal pressure nozzles utilized baffles to physically reduce spray obscuration levels and so avoid the use of empirical correction factors.
