Abstract Three different atomization techniques: direct pressure nozzles, air jet nozzles and spinning cylinder devices, were investigated to determine which would be most suitable for development into an airborne hygroscopic spray system used in cloud seeding. The system was to be capable of producing controlled droplet spectrums ranging from 20 micrometer MMD to 200 micrometer MMD, of an ammonium nitrate-urea solution to be used as a hygroscopic seeding material. The system was to be capable of atomizing the solution at rates of 2 liters per second. Tests were conducted under static no wind conditions and in a 110 m/s air stream. The atomization device that proved most suitable was a direct pressure impaction type nozzle. A prototype airborne spray system has been designed using this type of nozzle.
