Abstract
The objective of this study is to investigate the air entrainment and oxygen transfer characteristics of central-driven ejector with various ejector design parameters. The ejector design parameters are primary nozzle diameter, mixing tube length and diffuser angle. The entrainment ratio decreased with the primary nozzle diameter and diffuser angle, while the ratio increased with the mixing tube length. The trend of dissolved oxygen concentration with the diffuser angle and mixing tube length is equal to the result of entrainment ratio, however, the trend with the primary nozzle diameter is different to the result of entrainment ratio.
