Characterization of Instabilities of Sprays Generated by Multihole Effervescent Atomizers

Popis výsledku v původním jazyce

In some technical applications (e.g. fuel atomization in gas turbine combustors or burners) effervescent atomizers are more frequently being used. Effervescent atomization is a method of twin-fluid atomization that involves bubbling a small amount of gasinto the liquid before it is ejected from the atomizer. The advantages in comparison with common twin-fluid injectors are simple design and fine spray under low pressure and low mass air-liquid ratio. Nevertheless unstable behaviour of atomizer occurrsat some operational modes. Little effort has been so far made to resolve this problem, although spray stability in the large turndown ratio is usually one of the basic demands for atomizer design. The stability of the spray can significantly impact on the stability of the flame and on the formation of NOx. The objective of the submitted paper is a design of suitable method for spray instability measurements. It means to find an appropriate quantity for description of instabilities and th
