The effect of dense spray on drop size measurement by light scattering technology was studied using a Malvern instrument with five duplicated internal mixing airblast atomizers aligned with a laser beam. The correction factor data for multiple scattering were obtained. By regression analysis, an empirical equation was obtained that correlated the correction factor as a function of obscuration (OBS), Sauter mean diameter under dilute spray condition (SMD0 ), and drop size distribution parameter for Rosin-Rammler distribution under dilute spray conditions (N0 ). The experimental data showed definitely that the correction factor is not only a function of OBS and SMD0 , as proposed by Dodge, but also is a function of N0 . The correlation fits the experimental data very well, and can be used for practical purposes to correct the data from the Malvern drop sizer at high obscuration conditions.
