"Effervescent atomizers are based on mixing of gas with liquid prior to discharge. We describe the discharge of two-phase mixture and movement of droplets in gas jet using simple theoretical models, following with elucidation of droplets dynamics using experimental data for an effervescent spray. Discharge of the liquid-gas flow from the nozzle is described using a combination of two discharge models. Depending on operation conditions, 59\u201364% of the total discharged mass corresponds to Separated Flow Model and the rest to Homogeneous Flow Model. Discharge velocity of the liquid reaches 12\u201327% of the gas exit velocity. The liquid-gas velocity ratio is negatively correlated with gas-to-liquid mass ratio (GLR) and positively correlated with inlet pressure. Radial profiles of axial droplet velocity, as measured using Phase Doppler anemometry, are axisymmetric bell-shaped with a maximum in the centreline analogous to the profile defined for a simple gas jet which however is more flat near the centreline"@en . . .
