摘要：
The aim of this study was to experimentally investigate the mass transfer characteristics of air-water mixed jet with central nozzle ejector. Using the mass ratio, the mixed jet behavior discharged in a water tank, the mass transfer coefficient, and efficiency were analysed qualitatively. The mass ratio decreased with the primary flowrate, and the specific input power decreased with the mass ratio. Additionally, as the mass ratio increased, the transient length from horizontal jet to buoyancy jet, and the total penetration length of mixed jet decreased. Furthermore, with the increase in the mass ratio, the volumetric mass transfer coefficient decreased, while the mass transfer efficiency increased slightly and then decreased.
