dc.description.abstractA plunging water jet passing through the surrounding air entrains a large amount of air bubbles into a pool and forms a large submerged two-phase (gas-liquid) contacting area. This process is called air-entrainment or aeration by plunging water jets. Numerous studies were conducted with circular nozzles. This paper presents experimental investigation of flow characteristics of truncated and non-truncated circular nozzles. The flow characteristics such as volumetric air entrainment rate, bubble penetration depth and oxygen transfer efficiency are evaluated based on four major parameters which describe air entrainment at the plunge point: the nozzle diameter, jet length, jet velocity, and jet impact angle. In addition, new predictive equations are developed for the flow characteristics of truncated and non-truncated circular nozzles. Experimental results showed that truncated and non-truncated circular nozzles have very different flow characteristics. The truncated circular nozzles indicated a rather high quality with respect to bubble penetration depth, volumetric air entrainment and oxygen transfer. In aeration application, the truncated circular nozzles can be preferred due to different flow characteristics.en_US
