Original abstract
Effervescent atomization is characterised by bubbling a small amount of gas into the liquid upstream of the exit orifice, thereby forming a two-phase flow. Simplified transparent atomizer was used to observe two-phase flow of light heating oil and air mixture inside the atomizer. Specific flow patterns for different operating conditions were recognised and compared with results acquired using of published two-phase flow maps. As effervescent atomizer sprays tend to be unsteady under some operating conditions, a method for mixture instability measurement was developed and applied.
