Original Abstract

Effervescent atomization is becoming more and more frequently used in many industrial applications, ranging from pharmaceuticals, spray drying and coating to both internal and atmospheric combustion. With the expansion of computational fluid dynamics experimental data is needed to validate effervescent spray models. This paper aims to investigate axial evolutions of effervescent sprays while taking into account varying liquid mass flow rates and air-liquid ratios. Various types of axial evolutions are examined – cross-sectional, axial and boundary. The results are in agreement with author’s previously published papers and further accentuate the phenomena when SMD in the spray core decreases with axial distance whereas on the spray edge SMD increases. The result also confirm the inverse effect of GLR on mean drop sizes.
