An experimental study was conducted to investigate the atomization characteristics of spray from the effervescent atomizer, which has separated two aerator tubes. The atomization characteristics were examined through the influence of ALR and the changes of atomizer geometry such as nozzle orifice diameter, diffusion angle, mixing chamber volume. PDPA(Phase Doppler Particle Analyzer) was used to evaluate the atomization characteristics. During the experiments, the mass flow rate of liquid was kept constant at 2.8g/s and the mass flow rate of atomizing air was changed from 0.2 to 0.6g/s. Experimental results showed that SMD was not a linear function of ALR. While SMD is very sensitive to the changes of ALR, the changes of atomizer geometry had little effect on droplet mean diameter. As the effervescent atomizer with separated two aerator tubes is insensitive to the changes of atomizer geometry, it is expected that the effervescent atomizer with separated two aerator tubes is capable of requirements of many applications, without the drawbacks of atomization characteristics.
