Abstract

A spray nozzle which can produce extremely small droplet size (≤10 μm) finds relevance in drying, liquid-fueled engines, etc. In addition to the droplet size, its momentum too has equal importance in high-speed combustion systems like scramjets, pulse detonation engines for rapid mixing. Many of the nozzles which adopt standalone techniques (pressure, air-assist) fail to produce finer size droplets. Efforts have been made to hybridize two or more techniques to achieve the finer atomization. For instance, standard air-assist atomizer can be combined with effervescent/ultrasonic means to achieve further reduction in droplet size. This chapter presents the comprehensive aspects of such type of hybrid atomizers. Features such as mode of operation, benefits, shortcomings, areas of application are discussed in greater details.
