Effervescent atomizer is one of the most innovative atomizers and has been used in various applicationssuch as gas turbine combustors, consumer products, internal combustion (IC) engines and incinerators due to theiradvantages such as good atomization and insensitive to liquid viscosity. Performance of an atomizer could be measuredby their resultant spray produced by the atomizer. The influence of the geometrical parameters and operating conditiontowards the spray characteristics of any atomizer is very crucial since the change in the parameter will greatly affect theperformance. The factors influencing effervescent atomization are operating parameters and atomizer internal geometry.The purpose of this article is to study the dependence of effervescent spray unsteadiness on Effervescent atomizerinternal design.The result shows that the size of the droplets produced decreases with a decrease in the air injectionarea. This is due to the increase in atomizing air injection velocity that accompanies the decrease in the air injectionarea, which improves atomization. Short mixing chamber length provides slightly larger SMD and gives wider spraycone half-angle. The spray angle shows increment with the increase of discharge orifice diameter and with the increaseof the swirl generating vane angle.It is concluded that Effervescent atomizer is capable of providing a wide range ofspray patterns depending upon the application requirement by controlling various geometrical parameters.
