Characteristics of a Two-phase Flow Inside the Mixing Chamber of an Effervescent Atomizer

Popis výsledku v původním jazyce

Results of a recent study of the visualization of the two-phase flow inside an aerator of an effervescent atomizer are presented. 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. A simplified transparent model of atomizer has been designed in order to observe the two-phase flow of light heating oil and air mixture. High-speed camera Redlake MotionPro was used for visualization. Two-phase flow patteerns for specific atomizer operating conditions for vertical downward and horizontal pipe flow were recognised and the mixing processes inside an aerator were described and compared with published two-phase flow maps. The results show that observed two-phase flow patterns are not always in a good agreement with the findings acquired with use of two-phase flow maps. As the effervescent atomizer sprays tend to be unsteady under some operating conditions, a method for mixture unsteadiness m
