| dc.description.abstract | This paper deals with oxygen transfer by air entrainment by flow characteristics at the stepped drop structure. Nappe flow occurred at low flow rates and for relatively large step height. Dominant flow features included an air pocket, a free-falling nappe impact and a subsequent hydraulic jump on the downstream step. Skimming flow occurred at larger flow rates with formation of recirculating vortices between the main flow and the step corners. Oxygen transfer was found to be proportional to the flow velocity, the flow discharge, and the Froude number. It was more related to the flow discharge than to the Froude number. The stepped drop structure was found to be efficient for water treatment associated with substantial air entrainment. © 2006 by World Scientific Publishing Co. Pte. Ltd. All rights reserved. | - |
