This paper presents an experimental and statistical analysis of an effervescent atomizer. The spray da ta were obtained from experimental measurements by means of a Dantec phase/Doppler particle analyzer (P/DPA) a nd analytical and statistical analysis was performed u sing MATLAB software. The main goal of this work was to analyze the spray characteristics and to find analy tical functions that would fit the experimentally o btained drop size distributions. The fitted distributions were t hen discretized for modelling purposes and the mode lled spray was verified against the experimental data. The dis crete spray characteristics will be later used for combustion modelling.
