The objective of this work was to investigate the effects on spray dynamics of adding Surfactin to distilled water; four fan nozzles (F1-F4), one cone nozzle, and three bubbler (B1-3) nozzles were investigated at various pressure s. Twenty images were recorded for each nozzle, pressure, and spray solution (distilled water and surfactant solution) and analyzed for breakup length, droplet sizes, spray angle in the fan and cone nozzles, and ligament diameter in the bubbler nozzles. This data set provides each image's pressure, mass flow rate, and ambient relative humidity. For the fan and cone nozzle, it provides the volumetric mean diameter (D_V50), breakup length, and spray angle for each image. For the bubbler nozzle, it provides droplet diameter, breakup length, and ligament diameter from images. Data used in Stallbaumer-Cyr, E.M.
