The production of liquid sprays represents a key technology for a wide range of industrial proceses. Most applications currently use pressure or air‐assisted atomization, resulting in the production of polydisperese sprays. Recent advances in experimental and numerical techniques for investigating liquid spraying processes, however, have enabled a closer examination of parameter optimization, leading to the conclusion that in may cases, a much narrower size distribution, or even a monodisperse spray, may exhibit many advantages. Currently monodisperse droplet generators, or drop‐on‐demand generators, do not meet this challenge of producing monodisperse sprays, primarily owing to the very low volume flow rate of liquid which is atomized. In the present work, a monodisperse sprya generator is introduced, which overcomes this difficulty for many applications.
